摘　　要：针对目前生态功能区划仅从区域生态要素、生态敏感性与生态服务功能空间分异规律等方面考虑,而很少涉及景观格局特征与景观稳定度等景观生态学的内容;文章在景观生态学理论基础上,提出一套基于景观生态学的区域生态功能区划理论;一方面有助于生态功能小区的划分;另一方面可以弥补原有生态保育措施只考虑生态敏感性和生态服务功能重要性的不足,从景观生态学角度提出具有针对性的生态保育措施。文章将所建立的理论与方法用于重庆市长寿区生态功能区划,区划结果为:将重庆市长寿区划分为3个生态亚区,9个生态功能区和21个生态功能小区,与未考虑景观稳定度的生态功能区划相比,考虑景观稳定度的生态功能区划多了四个生态功能小区,而这四个生态功能小区的划出,有助于进一步针对具体问题,从生态学和景观生态学的角度提出生态保育措施,对重庆市长寿区环境保护和生态建设具有重要的指导意义。A new theory of ecological function regionalization is proposed based on landscape ecology, which makes up the shortages of ecological countermeasures that just consider eco-environmental sensitivity and importance of eco-service, but make concrete countermeasures for ecological zones from angle of landscape ecology. Taking Changshou District of Chongqing City as an example, the District was divided into 3 ecological sub-zones, 9 ecological function zones and 21 small ecological function zones. Comparing with ecological function regionalization, 4 more small ecological function zones were added, which will provide a scientific basis for implementation of master plan of regional eco-environmental conservation and construction.

关 键 词：生态功能区划 景观生态学 生态敏感性 生态服务功能价值重要性 景观稳定度 重庆市长寿区
