基于“三生”协调的郑州森林生态系统评价管理

Research on Urban Forest Ecosystem Evaluation and Management Based on the Coordination of"Ecological-production-living space"

森林生态系统评价是"三生"协调下森林可持续经营与管理的重要前提,以郑州国土空间为研究尺度,基于Arc GIS平台,从生态敏感性、生态恢复力及城市建设3个方面,选择25个指标,运用ARCGIS软件的层次分析法(AHP),建立三生空间协调分布下的森林生态系统复合评价体系并开展评价。结果表明:适宜建设开发区面积为2246 km^2,占29.90%;近郊生态缓冲区面积为3707 km^2,占49.36%;远郊生态保育区面积为1558 km^2,占20.74%,并提出相应的经营管理措施。试图从国土空间规划角度出发,统筹空间区划下的城市森林生态系统开发与保护、投入与效益,为森林资源保护、培育、恢复、营造和管理提供重要的调控理论及决策依据。

Forest ecosystem evaluation is an important prerequisite for sustainable forest management.Based on the ArcGIS analysis,this paper takes Zhengzhou as an example,choosing 25 indicators from ecological sensitivity,ecological resilience,and urban construction.A comprehensive evaluation system of the GIS-AHP forest ecosystem under the coordinated distribution of the ecological-production-living spaces is established and evaluated.The results show that the suitable construction and development area is 2246 hm^2,accounting for 29.90%;the suburban ecological buffer area is 3707 hm^2,accounting for 49.36%;the suburban ecological conservation area is 1558 hm^2,accounting for 20.74%.Corresponding management measures are also proposed.From the perspective of territory spatial planning,aiming to coordinate the development and protection of urban forest ecosystems,this paper provides theories and decision-making basis for forest resource protection,cultivation,restoration,construction,and management.
