【摘要】：由于我国现行的土地分类体系偏重于土地的生产、生活功能,对土地的生态特性考虑不够,将很多具有重要生态价值的土地归为未利用地,使得其因未得到应有的保护而被随意侵占。[目的]为了统筹推进经济、社会发展和生态文明建设,亟需明确各类土地的功能定位,尤其要在土地分类中加强对生态用地的考虑。[方法]文章以土地的生态、生产、生活功能为主导,同时兼顾其多功能性,将《土地利用现状分类》中的所有土地类型分为生态用地、生态生产用地、生产生态用地、生活生产用地四大类,构建"三生用地"分类体系。进而采用洛伦兹曲线和基尼系数的方法,以秦皇岛市昌黎县为例,分析了该县2014年"三生用地"的分布情况。[结论]结果表明:昌黎县生活生产用地、生产生态用地分布绝对平均;生态生产用地分布相对合理,主要分布于两山乡、十里铺乡;生态用地在全县各乡镇分布差距悬殊,主要分布在两山乡、昌黎镇及十里铺乡。基于县域四类用地在乡镇间分布的均匀程度差异,文章从土地利用结构调整和布局优化角度提出了相应的对策建议。
[Abstract]:Because the current land classification system in our country emphasizes on the production and living function of the land, the ecological characteristics of the land are not considered enough, so many land with important ecological value are classified as unused land. Make it because of lack of due protection and is arbitrarily encroached upon. [objective] in order to promote the economy, social development and ecological civilization construction, it is necessary to define the function of all kinds of land, especially to strengthen the consideration of ecological land in land classification. [methods] based on the ecological, productive and living functions of land, and taking into account its multifunction, all the land types in Land use status Classification were divided into ecological land, ecological production land and productive ecological land. Four major categories of living production land, the construction of "Sansheng land use" classification system. The distribution of "Sansheng Land" in Changli County of Qinhuangdao City in 2014 was analyzed by using Lorentz curve and Gini coefficient method. [conclusion] the results show that the distribution of production land is absolute average in Changli County, the distribution of ecological production land is relatively reasonable, mainly in Liangshan Township and Shilipu Township, and the distribution gap of ecological land in different towns and villages of Changli County is wide. Mainly distributed in Liangshan Township, Changli Town and Shilipu Township. Based on the difference of the distribution of the four types of land in the county area among the villages and towns, this paper puts forward the corresponding countermeasures and suggestions from the angle of the adjustment of the land use structure and the optimization of the layout.
