The Heilongjiang Jianbiannongchang area is located at the confluence of the Great and Lesser Xing’an Ranges.This area has a complex magmatic and tectonic evolutionary history that has resulted in a complex and diverse geological background for mineralization.In this study,isometric logarithmic ratio(ILR)transformations of Au,Cu,Pb,Zn,and Sb contents were performed in the1:50,000 soil geochemical data of the Jianbiannongchang area.Robust principal component analysis(RPCA)was conducted based on ILR transformation.The local singularity and spectrum-area(S-A)methods were used to extract information on mineralogic anomalies.The results showed that:(1)the transformed data eliminated the influence of the original data closure effect,and the PC1and PC2 information obtained by applying RPCA reflected ore-producing element anomalies dominated by Au and Cu.(2)The local singularity method can enhance the information of the local strong and weak slow anomalies.After performing local singularity analysis on PC1 and PC2,the obtained local anomalies reflected the local singularity spatial anomaly patterns related to Cu and Au mineralization in this area,which is an effective method for trapping ore-producing anomalies.(3)Furthermore,the composite anomaly decomposition of PC1 and PC2 was performed using the S-A method,and the screened anomalous and background fields reflect the ore-producing anomalies related to Cu and Au mineralization.This information is in agreement with known Cu and Au mineralization.(4)The geochemical anomalies with mineralization potential were obtained outside the known mineralization sites by integrating the information of oreproducing anomalies extracted by the local singularity and S-A methods,providing the theoretical basis and exploration direction for future exploration in the study area. 展开更多

Against the current background of global climate change, the study of variations in the soil carbon pool and its controlling factors may aid in the evaluation of soil's role in the mitigation or enhancement of greenhouse gas. This paper studies spatial and temporal variation in the soil carbon pool and their controlling factors in the southern Song-nen Plain in Heilongjiang Province, using soil data collected over two distinct periods by the Multi-purpose Regional Geochemical Survey in 2005-2007, and another soil survey conducted in 1982-1990. The study area is a carbon source of 1479 t/km2 and in the past 20 years, from the 1980s until 2005, the practical carbon emission from the soil was 0.12 Gt. Temperature, which has been found to be linearly correlated to soil organic carbon, is the domi- nant climatologic factor controlling soil organic carbon contents. Our study shows that in the relevant area and time period the potential loss of soil organic carbon caused by rising temperatures was 0.10 Gt, the potential soil carbon emission resulting from land-use change was 0.09 Gt, and the combined potential loss of soil carbon (0.19 Gt) caused by warming and land-use change is comparable to that of fossil fuel combustion (0.21 Gt). Due to the time delay in soil carbon pool variation, there is still 0.07 Gt in the potential emission caused by warming and land-use change that will be gradually released in the future. 展开更多

Objective In recent years, the rising incidence of cancer has increased patients’ living and economic burdens. This study analyzed the incidence and death due to malignant tumors in tumor registries in Heilongjiang province (China) in 2015 to provide a scientific basis for the prevention and treatment of malignant tumors in this province. Methods Data on tumor incidence and patient deaths were collected from seven tumor registries in Heilongjiang province (China) in 2015. According to the stratification of urban and rural areas and patient sex, the crude, standard, and accumulative rates (0–74 years of age) were calculated. The 2000 China Population Census data and Segi’s standard population were used to calculate the age-standardized rates. Results In 2015, the incidence rate of malignant tumors in Heilongjiang cancer registries was 259.90/100 000. The age-standardized incidence rates in the Chinese and world standard populations were 158.89/100 000 and 155.06/100 000, respectively, with a cumulative incidence rate (0–74 years) of 17.68%. The incidence of malignant tumors in urban areas was 273.55/100 000, while that in rural areas was 220.32/100 000. The incidence of malignant tumors in men was 270.89/100 000, higher than that in women (249.04/100 000). Lung cancer had the highest incidence, followed by breast cancer, liver cancer, colorectal cancer, and thyroid cancer. The mortality rate of malignant tumors in Heilongjiang cancer registries was 164.69/100 000. The age-standardized mortality rates in Chinese and in world standard populations were 95.29/100 000 and 94.35/100 000, respectively, with a cumulative mortality rate (0–74 years) of 10.44%. The mortality rate of malignant tumors in urban areas was 169.51/100 000, while that in rural areas was 150.72/100 000. The mortality rate of malignant tumors in men was 201.64/100 000, higher than that in women (128.21/100 000). Lung cancer had the highest mortality, followed by liver cancer, stomach cancer, colorectal cancer, and breast cancer. Conclusion Lung, liver, breast, and colorectal cancers were the most common cancers in Heilongjiang province, China, and should be considered the key cancer types for prevention and treatment. Moreover, the incidence of thyroid cancer is increasing, and thus early preventative measures should be implemented. 展开更多

Twenty-three secondary forest communities with different structure were selected in Mao'er Mountain National Park of Heilongjiang Province, China to study the relationship between diversity of forest plant species and environmental gradient. The forest plant species diversity was analyzed by the diversity index, and the environmental factors was quantified by the method of Whittaker's quantification of environmental gradient. Meanwhile, β-diversity indexes of communities were calculated with similar measurements. The results showed that the Shannon-wiener diversity index of forest plant species increased with the increase of the environmental gradient, and the β-diversity indexes of communities showed a liner increase along with the change of environmental gradient. 展开更多

The biodiversity was studied in 26 communities with different structures in Maoershan National Park and Liangshui Natural Reserve of Northeast Forestry University in Heilongjiang Province, China. Composition index (CI) was taken as a parameter to quantify the community dynamics, which can nicely describe forest community dynamics, meanwhile, the relationship between diversity and community dynamics were also investigated and analyzed. Results showed that the total number species of community, richness, evenness, and Shannon-Wiener diversity index were obviously different in every community. The richness decreased with the increasing CI of every community, which means richness was in inverse proportion to community dynamics. The Shannon-Wiener index of every community increased from the initial stage to the middle stage of succession, and then decreased in the climax stage. The coverage weighted foliage-height diversity index increased along with the increase of CI, which was similar as the oattem diversity. 展开更多

The livelihoods of farmers are responding to the mioroeconomic policies and result in many changes in the landuse pattern and landscape, and the farmer's attitude to the natural resources conservation, specifically in the land degradation. In order to find the relationship between the farmers' response to the microeeonomic policies and land degradation, the authors surveyed 120 household in three villages in the black soil zone in Heilongjiang Province. Based on the feedback of the questionnaires, the authors established a model to analyze the impact. The results demonstrated that land degradation was impacted by farmers behaviors in the process of the adjustment of agricultural structures in the city of Zhaodong. And the main factors acted on the land degradation were the agricultural labour education level, the transfer of the labour from agricultural production, the price of the agricultural production materials, and the land scale management. The authors put forward some suggestions for sustainable agriculture based on the analysis on the topic. 展开更多

Based on data of daily average temperature observed during maize growing period as well as data of different growing periods of maize at 24 meteorological stations in Heilongjiang Province from 1980 to 2010, changes in risk of chilling damage to maize since 1980 were analyzed. Initially, the risk of the hazard factor was calculated by adopting the criterion of "Comprehensive Decision System of Chilling Damage to Maize in Heilongjiang Province". Then, choosing the planting area of maize at 75 stations as the exposure degree index, risk zones of exposure degree were concluded. Afterwards, risk zones of maize sensitivity to chilling damage were outlined based on maize yield per unit area. At last, a comprehensive evaluation model of chilling damage to maize in Heilongjiang Province was established, and Heilongjiang Province was divided into 5 grades of risk zones according to the model. The results showed that compared with the period before 1995, the risk of chilling damage to maize was severer in the west area of Songnen Plain, and previous sub-low or medium risk of chilling damage to maize in the west of Sanjiang Plain changed into subhigh or hi qh risk since the middle 1980s. 展开更多

Four main dinosaur-bearing sites have been investigated in latest Cretaceous deposits from the Amur/Heilongjiang Region : Jiayin and Wulaga in China ( Yuliangze Formation), Blagoveschensk and Kundur in Russia (Udurchukan Formation). More than 90% of the bones discovered in these localities belong to hollow-crested lambeosaurine hadrosaurids: Charonosaurus fiayinensis at Jiayin, Amurosaurus riabinini at Blagoveschensk, Olorotitan arharensis at Kundur, and Sahaliyania elunchunorum at Wulaga. Flat-headed hadrosaurine hadrosaurids are much less numerous, but appear well diversified as well: Kerberosaurus manakini at Blagoveschensk, Wulagasaurus dongi at Wulaga, and a new genus at Kundur. Theropods are represented by shed teeth and isolated bones; isolated scutes and teeth discovered at Kundur are tentatively attributed to nodosaurids. Palynological studies suggest that these sites are probably synchronous with the Lancian' vertebrate localities of western North America, which represent the youngest dinosaur faunas in this area. However, the latest Cretaceous dinosaur assemblages are completely different in the Amur/Heilongjiang region (lambeosaurines abundant, ceratopsids absent) and in western North America (ceratopsids abundant, lainbeosaurines extremely rare or absent). This probably reflects some kind of geographical barrier between both areas by Maastrichtian time rather than strong differences in palaeoecological conditions. 展开更多

A new geological section recognized in Baishantou of Jiayin,Heilongjiang Province,China,was studied preliminarily in searching for the K/T boundary.An early Paleocene florule characrerized by abundant Tiliaephyllum tsagajanicum leaves and its associated plants,was collected from the Baishantou Member(new member representing the lower part of the Paleocene Wuyun Formation)overlying the possible K/T boundary.A tuff bed was found from the upper part of the Furao Formation(uppermost Cretaceous)in this section.The new findings imply that the K/T boundary is probable lying in the interval between the base of the Baishantou Member and the tuff bed,based on the correlation of the present strata with the stratotype of the Tsagajan Group spanning the K/T boundary in"Belaya Gara"of the Bureya Basin,Russia.The early Paleocene florule from the Baishantou Member and the early-middle Maastrichtian dinosaurs found from the Yuliangzi Formation underlying the Furao Formation suggest that the Baishantou section is more promising for searching for the K/T boundary in this area.Further studies of the section is needed,integrating paleontological,biostratigraphic,geochemical,paleomagnetic,and sedimentary research would benefit our understanding the mass extinction event and biotic recovery in the Heilongjiang River area,China,and even all of northeast Asia during the K/T boundary interval. 展开更多
