2) Ecological constraint theory
生态约束论
3) RS & GIS
生态约束力
1.
The paper,taking riverside area along Yangtze river in Hexian County in Anhui province as an example and villages and towns as the basic evaluation units,is supported with RS & GIS and adopts the regionalization method of assimilated dynamic clustering and mutex-similar matrix classification with eco-environmental restriction system and support system with economy-development condition.
以安徽和县为例,以乡镇为基本评价单元,运用生态足迹的理念和方法,构建了生态约束力评价体系;以遥感和GIS技术为支撑,构建了静态和动态的经济社会支撑力评价体系,采用"生态—经济社会支撑力"趋同性动态聚类和互斥性矩阵分类相结合的梯阶分区方法,将中部沿江县域划分为优先开发区、鼓励开发区、适度开发区、引导开发区、限制开发区和灰色区域六大类型,并对功能区类型静态和动态划分的综合集成方法进行了探索,使功能区类型划分更具科学性和前瞻性。
4) Eco balance constraint
生态平衡约束
5) the ecosystem condition control
生态条件约束
6) eco-environmental restriction
自然生态约束
1.
Supported with,it commenced with the two sides of eco-environmental restriction and economy-development support.
在GIS技术支撑下,从自然生态约束和经济开发支撑两方面,选择了山地面积比重、水网密度、湿地面积比重、主要河流长度、主要资源拥有量、交通可达性、人口学历层次、GDP等指标作为县域尺度空间主体功能分区评价因子,并通过象限图法划分县域主体功能区。

) were selected,adopting the regionalization method of eco-environmental restriction,there were 41 counties regarded as the basic units to be evaluated.
以GIS技术为支撑,从自然生态约束分区评价着手,以安徽沿江41个县市为基本单元,选择山地、水网、湿地、水环境容量等指标进行生态功能差异评价,经聚类归并以及兼顾功能区的完整连片,将安徽沿江地区划分为4个一级生态功能区1、4个二级生态功能区。
