The index has been given by experts' subjective assignment based on experience. Analytic hierarchy process has been used,making questionnaires of experts,using pairwise comparison and calculating the weight of each index. The weight of index in assessment would not only make quantitative evaluation on the whole situation of green store buildings,but also provide the foundation for compilation and revision.展开更多

The characteristics and key design points of constructed wetland under the ecological principles were explored, taking the Jingyue Lake in Zhongxiang City, Hubei Province for example, treatment processes were designed for different infl ow waters on the basis of site analysis to facilitate the water environment control and ecological landscape construction, ecological theories were applied to explore functional layouts and landscape designs of wetland, to build a favorable ecological environment of urban wetland and design outstanding wetland ecological landscapes.展开更多

Resolving the internal relations and dynamics ruling the association between regional vegetation and climate change is important to understand and protect the regional ecosystems. Based on vegetation, temperature and precipitation data of the Tibetan Plateau from 2001 to 2010, we analyze the spatial and temporal variations of vegetation cover over the past 10 years and discuss the vegetation response to climate change using empirical orthogonal function and singular value decomposition. Our results reveal the following:(1) vegetation cover gradually decreases from the southeast to the northwest of the Tibetan Plateau;(2) vegetation cover has increased on the Tibetan Plateau over the past 10 years, mainly in the central and eastern zones; and(3) a significant positive relationship was suggested between vegetation cover during growing season and the temperature in the entire region and with precipitation in the central and southern zones.展开更多
