重庆市域生态网络构建研究

Study on the Ecological Networks Construction in Chongqing

构建区域生态网络、联结生态用地,是维护区域生态过程完整、提升区域生态安全的必由之路。基于重庆市特殊的生态基础、生态价值及区域发展状态,在整体分析区域生态状况以及评估生态服务功能的基础上,识别出发挥重要生态服务功能的斑块,结合生态流流动空间及其过程,形成"斑块-廊道"模式的生态网络基础,通过网络结构分析方法,以生态服务高效发挥为指向,确认生态网络结构与形态,耦合城乡发展,构建了重庆市域生态网络,该网络达到了形态与功能的统一。同时,该项研究也优化了生态网络的构建方法。

Constructing ecological networks and connecting ecological lands is the key to maintain the integrity of regional ecological process and improve the regional ecological security. In this research,on account of the ecological basis,ecological value and regional development state in Chongqing,based on the overall analysis of the ecological status of the region and the evaluation of ecosystem service,major ecological patches were identified. Then,integrated with ecological flow space,the patch–corridor ecosystem networks model was developed. Lastly,by applying the network analysis method for improving ecological service efficiency,confirming the ecological network structure and form,combining the development urban-rural development,the structure and the pattern of the ecological networks of Chongqing were designed,which achieves the unity of form and function of the networks,and also optimizes the method of constructing ecological networks.
