By the methods of in situ investigation and regional ecological planning, the present ecological environment, ecosystem vulnerability, and ecological environment sensitivity in "Ji Triangle" Region were analyzed, and the ecological network of the study area was constructed. According to the ecological resources abundance degree, ecological recovery, farmland windbreak system, environmental carrying capacity, forestry foundation, and ecosystem integrity, the study area was classified into three regional ecological function ecosystems, i. e., east low hill ecosystem, middle plain ecosystem, and west plain wetland ecosystem. On the basis of marking regional ecological nodes, the regional ecological corridor (Haerbin-Dalian regional axis, Changchun-Jilin, Changchun-Songyuan, Jilin-Songyuan, Jilin-Siping, and Songyuan-Siping transportation corridor) and regional ecological network (one ring, three links, and three belts) were constructed. Taking the requests of regional ecological security into consideration, the ecological environment security system of "Ji Triangle" Region, including regional ecological conservation district, regional ecological restored district, and regional ecological management district, was built.
通过实地调查和区域生态规划方法，分析了“吉三角”地区当前的生态环境、生态系统脆弱性和生态环境敏感性，并构建了研究区域的生态网络。根据生态资源丰度、生态恢复情况、农田防风体系、环境承载能力、林业基础和生态系统完整性，将研究区域划分为三个区域生态功能生态系统，即东部低山生态系统、中部平原生态系统和西部平原湿地生态系统。在标记区域生态节点的基础上，构建了区域生态廊道（哈大区域轴、长春—吉林、长春—松原、吉林—松原、吉林—四平、松原—四平交通廊道）和区域生态网络（一环、三连线、三带）。考虑到区域生态安全的要求，构建了“吉三角”地区的生态环境安全体系，包括区域生态保护区、区域生态恢复区和区域生态管理区。
