【摘要】：生态用地是区域生态服务功能的主要供给者,对控制区域生态环境起到关键作用,开展生态用地分类与保护,对实现经济与生态协调发展、保障区域生态安全具有重要意义。以江苏省宜兴市为例,基于前人对于生态用地分类与土地利用现状分类衔接研究成果,提取土地利用现状中的生态用地,借助景观安全格局理论方法,通过系统分析水土保持、生物多样性保护、乡土文化遗产保护以及自然景观保护4个与生态用地相关的重要生态过程,运用最小累积阻力模型构建区域综合景观安全格局,并将综合景观安全格局与现状生态用地进行叠加,得到低安全水平、较低安全水平、中等安全水平以及高安全水平4种类型的生态用地,各类型面积分别占研究区生态用地总面积的32.07%、44.38%、22.07%以及1.48%,针对不同等级的不同生态用地类型,提出了划定禁止建设区、防止水体污染、建设高标准基本农田等针对性的保护措施与对策。研究结果为宜兴市的土地利用规划与管理、城市可持续发展等提供决策依据,为其他类似地区生态用地保护规划编制提供参考。
[Abstract]:Ecological land is the main provider of regional ecological service function and plays a key role in controlling the regional ecological environment. It is of great significance to carry out the classification and protection of ecological land to realize the coordinated development of economy and ecology and to ensure regional ecological security. Taking Yixing City, Jiangsu Province as an example, based on the previous research results of ecological land classification and land use status classification, the ecological land is extracted from the current land use situation, and the theory of landscape security pattern is used to systematically analyze soil and water conservation. Four important ecological processes related to ecological land use are biodiversity conservation, local cultural heritage protection and natural landscape protection. The minimum cumulative resistance model is used to construct the regional comprehensive landscape security pattern. The comprehensive landscape safety pattern is superposed with the present ecological land, and four types of ecological land are obtained, which are low safety level, lower safety level, middle safety level and high safety level. Each type of area accounts for 32.07% of the total ecological land area and 1.48% of the total ecological land area in the study area. According to different ecological land types of different grades, a no-construction area is proposed to prevent water pollution. Construction of high standard basic farmland and other targeted protection measures and countermeasures. The results provide a basis for the decision-making of land use planning and management, urban sustainable development and other similar ecological land conservation planning in Yixing City, and provide a reference for the compilation of ecological land conservation planning in other similar areas.
