摘要
科学识别生态保护和修复工作的重点区域具有重要意义。通过评估响水县生态系统的服务功能,分析存在的生态问题,利用MCR模型提出响水县生态安全格局的优化方案,探讨东部沿海典型县域生态保护和修复的重点方向。结果表明:①响水县的生态保护与修复工作应当关注三个主要生态问题:滨海湿地面积减少、河网水系连通性不足、部分区域耕地破碎化;②识别出151.9 km^(2)生态源地,集中在沿海区域;生成376.4 km生态廊道,呈“南北对称”;③优化构建出“一屏两核三带”的生态安全格局方案,并在此基础上划分出三个重点区域,提出保护滨海湿地、畅通河网水系等主要任务,建设海河联动的生态安全格局。本研究可为响水县的生态保护与修复工作提供科学依据。
Identifying key areas for ecological protection and restoration through scientific methods holds significant importance.By assessing the ecosystem service function of Xiangshui County,analyzing the existing ecological problems,using MCR model to put forward the optimization plan of ecological security pattern,and explore the key direction of ecological protection and restoration of typical counties in the east coast.The results showed that:①Three main ecological problems should be paid attention to in the ecological protection and restoration work in the study area:the reduction of coastal wetland area,the lack of connectivity of river network and water system,and the fragmentation of cultivated land in some areas;②The ecological source area of 151.9 km^(2) was identified,concentrated in the coastal area;376.4 km ecological corridor is generated,showing a“north-south symmetry”;③Based on optimizing and constructing the ecological security pattern plan of“one screen,two cores and three belts”,there are three key areas for ecological protection and restoration are identified,and the main tasks such as protecting coastal wetlands and unimpeded river network were proposed to build an ecological security system in which the sea and river are interconnected.This research can provide a thinking path and research experience for the ecological protection and restoration work and planning compilation of counties in the eastern coastal area.
