- 摘要:
评价道路生态廊道的生态位适宜度,可为确定各类景观面积和布局提供科学依据,从而优化道路生态廊道的景观格局。本次研究区为近郊型道路353省道(仪征段)两侧各1km范围的生态廊道,道路绿化景观有机拓展和融入周边的农田、湿地、丘陵和乡村,形成景观、产业、旅游的统筹规划和建设,是一条以线带面、综合规划的道路生态廊道建设综合体。借助地理信息系统(GIS)技术手段进行景观格局分析,通过建立生态涵养、旅游经济、农业生产三个方面相关生态位适宜度评价体系和模型,对研究区各区段的功能定位进行量化赋值研究,取其最大赋值作为该区段的主要功能发展方向,并由此确定景观的面积、布局和内容,实现景观格局的科学优化配置,促进景观资源的合理利用和可持续发展。 - 关键词:

Based on the ecological corridors with 1 km on each side of the 353 provincial highway (Yizheng section), the road landscape was organically expanded and integrated into the surrounding farmland, wetland, hills and villages to form overall planning and construction of landscape, industry and tourism, which is a road ecological corridor complex with line, surface and comprehensive planning. The paper analyzed landscape pattern on the basis of GIS techniques, and then constructed ecological niche suitability model by determining a factor system in terms of ecological conservation, tourism economy and agricultural production. The paper studied the quantitative functional orientation of each section, and determines the main function development direction of each section along the ecological corridor of 353 provincial highway with its maximum assignment, followed by determining the area layout and content of the landscape, so as to realize the scientific and optimal allocation of the landscape pattern and promote the rational utilization of landscape resources and sustainable development.
