【摘要】：针对承德市土地利用存在结构不合理、后备资源不足、经营粗放、生态环境恶化等问题,文章使用承德市2007~2015年统计年鉴以及土地利用变更数据等,通过定量与定性分析结合的方法,分析承德市的土地利用现状、土地利用结构以及土地利用速度变化。并借助主成分分析方法,分析承德市建设用地的驱动因素。结果表明:(1)土地利用现状具有开发程度适中、比例分配合理特征;(2)土地利用结构方面,农用地变化不大,耕地面积有所减少,园地、林地增幅较大,建设用地增长幅度也较大;(3)土地利用程度方面,承德市土地利用程度变化不大,总体来说呈现增强态势;(4)土地利用变化速度方面,水域、水利设施占地以及交通用地变化较大,耕地和草地变化程度较小;(5)土地利用变化的主导因素是经济发展、人口以及城镇化。由此提出调整土地利用结构,优化土地利用布局,提高耕地质量,转变土地经营方式,建设水土保持工程等措施,以促使土地利用生态化利用及土地可持续发展。
[Abstract]:In order to solve the problems such as unreasonable structure of land use, insufficient reserve resources, extensive management and deterioration of ecological environment in Chengde City, etc. Using the statistical yearbook of Chengde city from 2007 to 2015 and the data of land use change, the paper analyzes the present situation of land use in Chengde city by combining quantitative and qualitative analysis. With the help of principal component analysis, the driving factors of construction land in Chengde city were analyzed. The results showed that the current land use status of the city was moderate. Reasonable characteristics of proportional distribution; 2) in the aspect of land use structure, the agricultural land has little change, the cultivated land area has been reduced, the increase rate of garden land and forest land has been large, and the increase rate of construction land has also been larger; (3) in terms of land use degree, the degree of land use in Chengde City has not changed much, but it has shown an increasing trend on the whole; (4) in terms of the rate of land use change, the land occupied by water, water conservancy facilities and traffic land changed greatly, while the degree of change of cultivated land and grassland was relatively small. 5) the main factors of land use change are economic development, population and urbanization. Therefore, it is proposed to adjust the structure of land use, optimize the distribution of land use, improve the quality of cultivated land and change the mode of land management. Construction of soil and water conservation engineering to promote the ecological use of land and land sustainable development.
