In our past energy planning system, city energy planning drew up by the city energy department is mainly energy demand and energy supply plan, stresses less in subjects and problems of city energy policy, city energy use-pattern, city saving energy and city energy-using contamination, etc. Energy planning is just a department of regional industry planning, not a comprehensive strategic planning. It...
The urbanization is an inevitable result of the development of human being and progress across the world. With the rapid development of urbanization in China, the ecological environment problems related to the urbanization processes have become more and more serious due to the increasing air pollution emission, which becomes the potential threat to the sustainable development of Guangzhou, China....
The main objective of this study was to make a pollution regionalization of soil heavy metals in A city, an area with rapid economic development in Yangtze River Delta of China. Therefore, the spatial distribution of soil heavy metals was firstly estimated by optimal space method using 126 data points and performed using ArcGIS9.2 software. The areas of different content grade were computed by overlay...
This study attempts to evaluate the spatial variability characteristic of soil heavy metals in different industrial types. Therefore, concentrations of heavy metals in soils with different distances from solid, liquid and gas point source and nonpoint source were measured in Yixing, an area with intensive industrialization in Yangtze River Delta of China. The results show that 1) the enrichment of...
Apply approach of time-space transfer and take soil covered in different years as a carrier, this paper constructed the historical record of soil heavy metals (HMs) content during 1950 to 2006 in Yixing city, an area with rapid socio-economic development in Yangtze River Delta of China, and discussed the impact of socio-economic development on soil HMs content and pollution indexes with gray correlative...
Urban green system plays a vital role in the urban sustainable development. This study, using analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) models, taking provinces in China as unit, has made analysis and thus carried out a classification of the landscape construction level of provinces in China from a macroscopic view. The results show...
