中国少数民族地区防风固沙功能区的研究

Study on Windbreak and Sand-control Functional Areas in Minority Regions of China

本文对中国少数民族地区的防风固沙功能区进行研究,了解其成因和现状,并根据相关准则对沙漠化进行现场评价,选取气候因素及地质背景作为生态因子,分析区域沙漠化敏感性程度、少数民族地区沙漠化的土地类型和面积,依据沙漠化直接影响人口数量来评价防风固沙重要性,并划分了对四类少数民族防风固沙功能区,同时分析了功能区的主要特点及存在的沙漠化问题,提出了防风固沙的政策体系和技术体系,为少数民族地区社会经济与生态环境的和谐发展提供了技术支持.

Based on the research of windbreak and sand-control functional areas in minority regions of China,we evaluated desertification according to relevant guidelines.Then,we analysis the regional desertification level of sensibility with selecting climate factor and geological background as a factor of ecology and investigating the type and area of desertification land in the minority regions,based on the desertification direct impact on the population of desertification to evaluate the importance of precautions.We divide the four categories minority functional areas of windbreak and sand-control and analysis the main characteristics and desertification problem,Finally,put forward the policy system and technology system for the minority areas harmonious development between socio-economic and environment.
