基于适宜性分析的辽河保护区土地利用规划

基于保护河流完整性原则，同时考虑满足人类需求，利用适宜性分析方法对辽河保护区进行了土地利用规划。通过分析河流纵向物理特征和横向结构，将辽河保护区纵向分为8段，横向分为4个区。利用适宜性分析并结合河流横向特征，对辽河保护区的土地进行规划，共有用地类型11类，按面积由大到小分别为河岸带生物多样性用地、辽河口湿地用地、生产用地、入干水质控制用地、大坝防洪安全用地、河道用地、高生态功能湿地用地、险工险段低风险用地、生态水面景观用地、水库湿地用地和城市景观用地，分别占总面积的38.71%、22.56%、12.17%、7.85%、4.20%、3.62%、3.22%、2.79%、1.89%、1.88%和1.12%。近80%的土地用于与构建水生生境相关的土地利用类型，体现了保护区生态保护的功能定位。

Land Use Planning in Liaohe Conservation Area Based on Land Suitability Analysis

To protect the riverine integrity and meet people’s use for river, land use planning was made based on land suitability analysis in Liaohe Conservation Area. The river system was classified longitudinally and laterally based on the riverine physical features, e.g. sinuosity. The whole Liaohe main river was classified into 8 segments in the longitudinal direction and 4 zones in the lateral direction. Land use planning in Liaohe Conservation Area showed that there were altogether 11 land types, including land for riparian biodiversity conservation, land for river estuary wetland, land for production, land for water quality control into mainstream, land for dam flood-proof safety, land for river channel, land for high eco-function wetland, land for risk-reduction of danger works and danger section, land for ecological water surface landscape, land for reservoir wetland and land for urban landscape, respectively accounting for 38.71%, 22.56%, 12.17%, 7.85%, 4.20%, 3.62%, 3.22%, 2.79%, 1.89%, 1.88% and 1.12% of the whole area. Nearly 80 percent of the whole area was used for land related to aquatic habitat which could embody the function orientation of the river conservation area.
