摘　　要：开展国土绿化行动、建设并筑牢生态安全屏障是我国建设生态文明的重要举措之一。当前,长春经济圈西北部地区生态问题相对较为突出,已成为区域生态安全的短板所在。以该区域为研究区,基于其生态本底特征和主要生态问题,构建了包含区域生态屏障因子的景观生态风险定量评价方法,研究结果表明:①研究区生态屏障建设的关键区域包括景观生态风险相对较高地区和生态屏障建设相对薄弱地区2类;②高风险区和较高风险区主要分布在农安县中部等地区,分别占研究区总面积的1.25%和1.74%;③生态屏障建设相对薄弱地区是引入生态屏障因子后景观生态风险提高的区域,主要分布于长岭县与农安县交界地带,约占总面积的1/4。综合问题导向和目标导向,从加强景观生态风险管控、推进薄弱地区生态建设2方面分别提出了具有针对性的生态安全屏障建设策略,助推长春经济圈高质量、可持续发展。研究可为区域生态屏障建设研究和相关生态规划提供较为可行的思路,并为国土空间格局优化提供有益的参考。Carrying out territory virescence action and ecological barrier construction is one of the important measures of eco-civilization construction in China.At present,the ecological problems in the northwestern part of Changchun economic circle are relatively prominent,which have become the shortcoming of regional ecological security.Based on the ecological background characteristics and main ecological problems of the study area,the authors constructed a quantitative assessment method for landscape ecological risk including ecological barrier factor.The results are as follows:①The key areas of ecological barrier construction in the study area include two categories:areas where landscape ecological risk is relatively high,and areas where ecological barrier construction is relatively weak;②the areas with relatively high landscape ecological risk are mainly distributed in the central part of Nong’an County,accounting for 1.25%and 1.74%of the total area of the study area;③the relatively weak areas of ecological barrier construction are the areas where the landscape ecological risk increases after the introduction of ecological barrier factor,mainly distributed in the border zone between Changlin County and Nong’an County,accounting for about 1/4 of the total area.Based on the comprehensive problem-oriented and target-oriented approach,the authors put forward strategies from two aspects of strengthening the control of landscape ecological risk and promoting ecological construction in relatively weak areas,so as to promote the high-quality and sustainable development of Changchun economic circle.This study provides not only a feasible idea for the study of regional ecological barrier construction and related ecological planning but also a useful reference for the optimization of land space spatial pattern.
