摘要:

采用加权指数求和法,从生态服务功能、景观生态空间格局以及生态敏感性3方面建立生态重要性空间识别指标体系,通过专家咨询和层次分析法确定各评价指标分级赋值标准和权重,结合GIS空间分析功能对“延龙图”(延吉-龙井-图们)地区生态用地的生态重要性进行空间识别,将其划分为3个级别:极重要、重要和一般重要,以反映不同生态用地保护级别和建设管制要求。结果表明,延龙图地区极重要生态用地占生态用地面积的25.720%,主要为耕地、林地和水域;重要生态用地占生态用地面积的39.500%,主要为林地和耕地;一般重要生态用地占生态用地面积的34.780%,以林地为主。

Abstract:

By using the weighted index summation method, the study applied ecological service function, landscape ecological spatial pattern and ecological sensitivity as indicators to determine the ecologically important space of urban ecological lands. Applying the research method of expert consultation and analytic hierarchy process(AHP)to determine both the evaluation criteria and the weight of the evaluation index, and combining spatial analysis of GIS, this article identified the ecologically important space of urban ecological lands in Yanji-Longing-Tumen area. They are categorized into three degrees, i.e. very important, important, generally important, which reflect the protection levels of different ecological lands and the requirements of construction control. The results showed that the very important ecological lands in Yanji-Longing-Tumen account for 25.720%, most of which are cultivated lands, forest lands and water area. The important ecological lands account for 39.500%, most of which are forest lands and cultivated lands. The generally important ecological lands account for 34.780%, which are mainly forest lands. Each of the three types of ecological land had its unique characteristics that required protection by adopting corresponding measures.This study is helpful to trace out the relationships between landscape pattern and ecological process,and provides insights for ecological planning and designing of land consolidation in this area.

Key words: urban ecological lands, ecological importance, space identification, Yanji-Longing-Tumen Area
