生态系统理论与方法在城市用地评定中的应用——以湖南省常德市为例

The Application of the Ecological System Theory and Method on the Urban Land Evaluation

城市用地评定的传统方法多采用分项图幅叠加分析法 ,它的缺陷在于指标的选取数量不宜过大 ,尤其是量化指标 ,指标总数以 4个以下为宜 ,否则 ,影响评定结果的精度。针对这种情况 ,在常德市城市用地适宜性分析中广泛选取可量化指标 ,初步运用了融因子生态学分析方法、景观生态学方法及生态图法于一体的生态系统理论与方法 ,并且在城区生态环境容量允许的条件下提出一些指导城市近期发展的定量指标。

the traditional method of urban land evaluation is the map superposition analysis,the disadvantage is the number of index would be restricted under four.Thispaper adopts the theory and method of ecological system,which integrate with ecological factor analysis,landscape ecological analysis,and ecological map analysis.It brings forward some quantification index to guide urban development in the mear future.
