基于生态敏感性评价的山水型旅游度假区保护性开发建设与调控对策OACSTPCD

The protection development and construction of tourist resort resources are the basic requirements of national ecological civilization construction.This paper takes the east district of Nanjing National Laoshan Forest Park as the research object.The aim is to provide the direction and countermeasure of eco-green development in tourism resorts.Based on GIS spatial analysis,an ecological sensitive evaluation system composed of landform,land use,forest ecosystem,wetland ecosystem,and biodiversity was established.The single factor and the comprehensive ecological sensitivity evaluation were carried out with a 30 m×30 m grid evaluation unit.The results showed that the ecological sensitivity in the study area is higher on the whole.In the single factor ecological sensitivity evaluation,the land use structure and development intensity as well as forest patch area and number in forest ecosystem have obvious effects on the ecological sensitivity degree.In the comprehensive ecological sensitivity evaluation,the extremely sensitive and highly sensitive areas accounted for 44.79%of the study area.The moderately sensitive areas accounted for about 17.20%.The mildly sensitive areas accounted for 17.16%and the non-sensitive areas accounted for 20.85%.The extremely sensitive areas and highly sensitive areas are distributed in the ecological conservation area and core landscape area of Nanjing National Laoshan Forest Park,the north and south slopes and hilltops of Laoshan Mountain,and the water conservation areas such as Foshou Lake.To construct the spatial pattern of coordination between development and protection,five countermeasures and suggestions are put forward,including prohibition,restriction,control,and support.
