规划环评中环境影响分析SD模型应用——以四川川南某县县城总体规划环评为例

Application of environment affecting analysis SD model in environment evaluation project

规划环评是一种兼具战略性和前瞻性的环境影响评价形式,长时效和动态性是规划环境影响的突出特征。为了在规划环评中更准确地对环境影响进行分析和评价,以川南某县县城总体规划为例,运用系统动力学模型对规划实施过程中环境影响进行模拟、分析和评价,这是将SD模型应用在相对微观地域上的一次尝试。

Environment Evaluation Project is a form of environmental affect evaluation, which is strategic and forward-looking. In order to make an accurate analysis and evaluation of environmental affect, the essay takes a county in south Sichuan Province as example to illustrate how to apply the System Dynamic Model (SD Model) to the general planning of the county. The SD Model can be used to imitate, analyze and evaluate the environmental affect during the enforcement of the general plan. It is a new attempt of applying the SD Model in microcosmic region and level.
