The development of relic and museum tourism products is not only the inheritanceof culture and the protection of cultural relics, but also the promotion of tourism consumption under thebackground of cultural tourism integration, which has promoted the development of regional economy.With the relic and museum tourism resources in Shandong Province as the research object, through theanalysis of its resources, market and products, this paper put forward three applicable modes of relic andmuseum tourism product development, including independent development, joint development, and artauthorization, and proposed specific suggestions around the three modes.展开更多

[Method] The daily minimum surface temperature ≤ 0 ℃ in autumn or spring was as the frost index. Based on the daily minimum surface temperature data in 67 meteorological observatories of Shandong Province during 1961-2008, the variation characteristics of first, last frost dates and frost-free period in Shandong Province were analyzed by using the climate diagnosis analysis method. [Result] The climate characteristics of first, last frost dates and frost-free period had the obvious geographical differences in Shandong Province in recent 48 years. The extreme differences of first, last frost dates and frost-free period were all above the three times of their standard deviations. It illustrated that the dispersion degrees of first, last dates and frost-free period were all very big. The average first frost date postponed with 1.99 d/10 a velocity in Shandong Province in recent 48 years, and the last frost date advanced with 1.46 d/10 a velocity. The postponing range of first frost date was bigger than the advancing range of last frost date, and the frost-free period prolonged with 3.42 d/10 a velocity. Seen from the interdecadal variations, the first frost date started to obviously postpone, and the last frost date obviously advanced since the 1990s. The frost-free period also started to obviously prolong since the 1990s. [Conclusion] The research provided the certain reference for the predication, prevention of frost disaster and the structure adjustment of crops.展开更多

Studying the territorial inequality of the net income per peasant was an emphasis of this paper,and Shandong Province was pointed as the case study region. By the help of logistic regression,it could be found that the special distribution of the net income per peasant in Shandong Province was affected by three factors:distance to No.308 National Highway,distance to the coastline in the east of Shandong Province,and urbanization rates. Based on the decomposition of Gini index,the net income per peasant was divided into four parts,and it was found that the income from family business and salary were the two major sources of income. As to the mechanism for income inequality,it was proved that urbanization was still the key factor. In order to reduce income inequality,the local governments should promote urbanization through improving road networks,such as building highways,which could connect rural areas with the major nodes such as big cities and the port cities in the east.展开更多

文摘With the development of the tourism year,tourism fever has become an emerging vocabulary among the public.However,the maintenance of a good ecological environment is the basis for maximizing the benefits of resources and the environment and developing tourism industry.In this paper,forest land,wetland coverage area and urban air quality were as the indicators of ecological environment quality,and the correlation between ecological environment quality and the number of inbound tourists and tourism income as well as the number of domestic tourists and tourism income in Shandong Province was analyzed.The results show that the overall ecological environment quality of Shandong Province has been continuously improved since 2008.By 2015,the forestry coverage rate increased to 24%,and the wetland area also expanded to 173 hm2.The total tourism income of Shandong Province continued to increase from 245.22 billion yuan in 2009 to 587.80 billion yuan in 2014,and the number of foreign tourists also rose from 3.10 million to 4.457 million.Typical eco-environmental quality indicators such as forest area and forest greening rate had a significant linear correlation with tourism income,and the correlation coefficients were all higher than 0.85.The results can provide relevant scientific reference for the future development of ecotourism and the protection of ecological environment.

文摘Taking 68 national wetland parks(including pilot sites)in Shandong Province as the research objects,three time sections of 2011,2014 and 2017 were selected,to analyze the spatial distribution characteristics of national wetland parks in Shandong Province by using geographic concentration index,imbalance index and standard deviation ellipse method,and explore the infl uencing factors by using SPSS stepwise regression analysis.The results show that the spatial distribution of national wetland parks is extensive but unbalanced,with more in central Shandong and less in eastern Shandong,and the distribution of other regions is relatively uniform.National wetland parks in Shandong Province are distributed along the northeast-southwest direction and are increasingly moving east-west direction.The impacts of natural factors such as topography,hydrology and climate on the spatial distribution of national wetland parks are consistent.At the same time,human factors such as economic environment,traffi c accessibility and population status also play an important driving role.

文摘Taking Shandong province,one of China’s first batch of circular economy pilot provinces,as an example,this paper summarizes some types of regional green innovation system models through the cases study and retrospective reasoning and retrospective approaches.The models mentioned above include(1)the innovation system model of green animal husbandry in coastal small towns,(2)the green innovation system model in intravenous industry park,(3)the green innovation system model in coastal hi-tech industrial development zone based on the development of eco-industrial and low-carbon industries,(4)the green innovation system model in coastal economic&technological development area based on the development of ecological arterial industry and the ecological intravenous industry through the waste recycle inside and outside the area,(5)the green innovation system model of coastal harbor economic and technological development area based on constructing tiny-medium-macro circulation,(6)the green innovation system of reformed coastal economic and technological development zone turning to the recycling marine industry innovation,and(7)the green innovation system model of high-tech industry development zone tending to recycling innovation of biological industry.This paper aims to analyze the characteristics of these models,the formation mechanism,and further to discuss their implications for greening the same type of regional innovation systems.
