On the basis of collecting 39 surface soil samples in Nanjing Liuhe Chemical Industrial Park as well as its surrounding area, and determining the total contents of Cu, As, Pb, Hg, Cd, this article evaluated the pollution index of soil heavy metals with the application of single factor index method and Nemero pollution index method. Meanwhile, the authors used Ordinary Kriging Method to draw the spatial...
The intensity allocation criteria of carbon emissions permits and its influence on China’s regional development are analyzed through the 30-province/autonomous region computable general equilibrium (CGE) model. Simulation results show that: industrial intensity criteria without taking regional economic development into account deepen the unbalance of regional economic development; regional intensity...
To reveal the spatial variability of soil heavy metals under the influence of urban expansion, Yingxing city of Jiangsu province was selected as study area. Three transects were arranged in the urban-rural ecotone. 24 surface soil samples were collected. And the contents of heavy metals including Hg, Pb, Cu and Zn were measured and analyzed. The results were as follows: (1) Hg contamination and Pb,...
This paper collected soil samples on provincial highway of Qiting of Yixing City at the leeward of the wind to study the space diversity condition of soil heavy metal pollution at the side of the road traffic under the influence of traffic. The results shows that: (1) Contents of Pb and Cu in the farmland soil on both sides of transport road existed accumulative phenomena and they were affected by...
The main objective of this study is to discuss the quantificational risk assessment model of urban land reserve planning. Based on the proposed model, the risk of urban land reserve planning in Nanjing was evaluated by using literature data and empirical analysis. The results show that the whole situation of the risk of urban land reserve planning in each district of Nanjing was in bad situation....
