秦岭北麓(西安段)生态红线划定研究

TUDY ON THE ECOLOGICAL RED LINE IN THE NORTH OF QINLING MOUNTAINS(XI'AN SECTION)

以秦岭北麓(西安段)为研究对象,在研究分析秦岭地区生态环境现状特征的基础上,利用ArcGIS软件,重要生态功能区评价指标选取生物多样性保护、水源涵养2项评价因素开展生态系统服务功能重要性评价,划定重要生态功能区红线;根据地方相关法规和规划,划定禁止开发区红线。将重要生态功能服务区红线与禁止开发区红线叠加,最终划定秦岭北麓(西安段)生态功能红线。其中,重要生态功能区水源涵养保护红线区面积达2 157 km^2,占全区总面积41.5%;禁止开发区范围面积约2 076 km^2,占全区总面积39.9%。叠加构成秦岭北麓(西安段)的生态红线区总面积3 157 km^2,占区域总面积的60.7%。秦岭生态红线范围的划定为秦岭生态环境保护提供理论基础。

Taking the northern foot of Qinling （Xi＇an section） as the research object,Based on the analysis of the status of the ecological environment in Qinling area, the evaluation of the importance of ecosystem service function was carried out by using ArcGIS software to select the evaluation factors of biodiversity conservation and water conservation, and the red line of important ecological function area was designated.According to local relevant laws and regulations, planning to prohibit the development zone red line.Will be important ecological function service area red line and prohibit the development zone red line superimposed, and finally delineation of the Qinling Mountains （Xi＇an section） ecological function red line.Among them, the important ecological function area of water conservation and protection of red line area of 2 157 km^2, accounting for the region a total area of 41.5 %; prohibit the development area of about 2 076 km^2, accounting for the region a total area of 39.9 %. The total area of the ecological red line of the Qinling Mountains （Xi＇an section） is 3 157 km^2, accounting for 60.7 % of the total area. The definition of ecological red line of Qinling Mountains provides the theoretical basis for Qinling ecological environment protection.
