【摘要】：为协调工业化、城镇化、经济快速发展与生态保护之间的矛盾,需要在土地分类中加强对生态用地的考虑。本研究以西藏普兰县为例,基于土地利用多功能性和主体功能性理论,建立了包含生态用地、生态生产用地、生产生态用地和生活生产用地在内的普兰县"三生用地"分类体系。为便于该体系的应用,将"三生分类"体系与土地利用现状分类进行对接,形成了普兰县"三生分类"用地提取方法。得出规划基期年普兰县生态用地、生态生产用地、生产生态用地和生活生产用地的面积分别为675 653.44、642 039.18、677.00和1 034.93 hm2,各占全县土地面积的51.21%、48.66%、0.05%和0.08%。在分析普兰县"三生用地"现状的基础上,根据上位规划、现状经济发展和各用地部门的需求,对普兰县土地资源进行了优化配置,对于生态环境安全有较高价值的生态功能用地、河流与湖泊用地面积保持不变,牧草地、用材林地面积则都有增加,建设用地主要占用的是生态容纳用地中的裸地和荒草地等,最大程度地对生态环境进行了保护,为生态文明建设和土地利用总体规划提供指标控制的科学依据。
[Abstract]:In order to coordinate the contradiction between industrialization, urbanization, rapid economic development and ecological protection, it is necessary to strengthen the consideration of ecological land in land classification. Taking Plan County in Tibet as an example, based on the theory of multifunction and subject function of land use, the author established ecological land and ecological production land. The classification system of "Sansheng Land" in Pu'an County, including production ecological land and living production land. In order to facilitate the application of the system, the "Sansheng classification" system was connected with the current land use classification, and the method of land extraction from the "Sansheng classification" in Pulan County was formed. The results show that the area of ecological land, ecological production land, production ecological land and living production land are 675 653.44642 039.18677.00 and 1 034.93 hm2, respectively, accounting for 51.21% and 0.08% of the county land area respectively. On the basis of analyzing the present situation of "Sansheng land use" in Pulan County, according to the upper planning, the current economic development and the demand of various land use departments, the paper optimizes the allocation of land resources in Pulan County. For the ecological function land with high value for ecological environment security, the area of river and lake land remains unchanged, the area of pasture land and timber forest land increases, and the construction land mainly occupies bare land and barren grassland in ecological accommodation land, etc. The ecological environment is protected to the greatest extent and the scientific basis of index control for the construction of ecological civilization and the overall planning of land use is provided.
