摘要/Abstract

摘要： 利用实际调研走访与区域生态规划相结合的研究方法，对“吉三角”区域生态环境现状、生态系统脆弱性、生态环境敏感性等进行了分析，并构建了研究区生态网架.结果表明：依据生态资源丰富度、生态恢复性、农田防护林体系、环境承载力、林业基础、生态系统完整性等因素，可将研究区划分为东部低山丘陵生态区、中部平原生态区和西部平原湿地生态区3种区域生态功能区;在对研究区生态节点进行标识的基础上，构建了区域生态廊道（哈大线区域轴带、长春-吉林、长春-松原、吉林-松原、吉林-四平、松原-四平交通廊道）及区域生态网架（一环、三核、三带）;基于区域生态安全的要求，建构了包括区域生态保育区、区域生态恢复区和区域生态治理区在内的“吉三角”区域生态安全格局框架.

Abstract: 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.

Key words: Pseudomonas, calcium chloride transformation, orthogonal experimental design, transformation efficiency.
