辽河三角洲湿地资源与区域持续发展

辽河三角洲湿地面积在、类型多、景观结构复杂多样，在该区经济发展中发挥巨大作用，利用遥感和ＧＩＳ技术，在建立辽河三角洲湿地资源分类系统基础上，对该区湿地资源现状与分布特征进行研究，该区现有湿地３１４８５７ｈｍ＾２，占全市总面积的７９．５％。其中天然湿地１５９９１９ｈｍ＾２，占总湿地面积的５０．８％，人工湿地１５４８３８ｈｍ＾２，占总湿地面积的４９．２％，多年来的区域资源开发活动，使该区湿地面积和景观结构发生很大变化，湿地生态功能变受到严重影响和威胁，本文结合区域湿地资源与景观结构的动态变化状况，系统分析了区域湿地生态系统功能及受影响状况，并进一步提出区域资源开发与湿地保护及可持续发展对策。

Study on Wetland Resources and Regional Sustainalbe Development in Liaohe Delta

With a large area, various types and complex landscape structure, wetlands in the Liaohe Delta have many benefits to the regional economic development. Based on the classification system of wetlands, the present situation and distribution characteristics are studied through RS and GIS techniques. There are 314,857 hm 2 of wetlands, which account for 79.5% of the total urban area; among which there are 159,919 hm 2 of natural wetlands and 154,838 hm 2 of artificial wetlands, accounting for 50.8% and 49.2% of the total wetland area, respectively. Because of the regional resources exploitation for many years, wetlands have changed a great deal in area and structure. Some strategies are put forward in this paper to protect the ecological function of wetlands and solve the problems of the sustainable development between resources exploitation and wetland protection.
