江苏阳澄湖重要湿地生态红线典型区监测研究

Study on Typical Ecological Red Line Monitoring of the Important Wetland in Jiangsu Yangcheng Lake

生态红线是指为维护国家和区域生态安全及经济社会可持续发展具有重要战略意义,必须实行严格管理和维护的国土空间边界线。结合地理国情普查工作确定生态红线区分类体系,建立了一套以地理国情数据为基础、基于多源数据的生态红线及监测方案。随后应用该方案,选取江苏阳澄湖重要湿地为监测区,提取该区域2005年以来生态红线覆盖现状,开展监测区统计分析与评价工作。研究表明,阳澄湖重要湿地自2005年以来随人工用地增长、自然景观持续下降,导致生态指数下降,且生物多样性持续下降;应冻结生态红线保护区范围内人工用地开发活动,对自然地类加大保护力度,从而维护该区域生物多样性。

The ecological red line refers to the national spatial boundary line,which is strategically important for safeguarding national and regional ecological security and sustainable development of economy and society,must be strictly managed and maintained.According to the census geographic conditions,the ecological red zone classification system is determined,and a set of ecological red line and monitoring scheme based on multi-source data in geographic conditions established.Then applying the scheme,extracting Jiangsu Yangcheng Lake wetlands as the monitoring area which covering the ecological red line situation in this area since 2005,the statistical analysis and evaluation monitoring area of work is carried out.Research shows that,since2005,artificial landscape in Yangcheng Lake wetland is growing and natural landscape is declining,which caused ecological index falling and biodiversity declining.So,the artificial land development in ecological red line protection area should be freeze and natural landscape protection should be increased,thereby protecting the biodiversity.
