广西北部湾经济区土地利用变化分析
|
摘要
广西北部湾经济区的开放开发,不可避免地伴生着土地资源的利用,如何合理高效地利用土地资源成为了当前该区域研究的热点议题。文章科学地分析并定量识别土地利用的演变,对于提高广西北部湾经济区土地利用效率水平,促进区域的可持续发展有着重要的意义。选取广西北部湾经济区2008年、2012年、2016年三期Landsat7 TM、Landsat8 TM遥感影像作为遥感解译的基础数据,运用探索性空间数据分析(ESDA)方法,从结构变化、数量变化、程度变化、速率变化、转移变化等五方面对广西北部湾经济区整体的土地利用时空演变格局进行分析。结果表明,广西北部湾经济区土地利用存在以下问题:(1)人均耕地少、土地集约利用水平低;(2)土地利用区域性差异大;(3)建设用地占用耕地比例过大;(4)建设用地扩张速度过快。
With the further development of Guangxi Beibu Gulf Economic Zone, the use of land resources is inevitable. How to use the land resource rationally and efficiently has become a hot topic in this region. It is of great significance for improving the land use efficiency and promoting the sustainable development of Guangxi Beibu Gulf Economic Zone to analysis scientifically and identifies quantitatively the evolution of the land use. LANDSAT7 TM and LANDSAT8 TM remote sensing images of Guang Xi Beibu Gulf Economic Zone in 2008, 2012 and 2016 were selected as the basic data of remote sensing interpretation. Base on the ESDA, the spatial and temporal evolution pattern of land use in GuangXi Beibu Gulf Economic Zone was analyzed in terms of structural change, quantity change,degree change, rate change and transfer change. The results show that the land use of GuangXi Beibu Gulf Economic Zone has the following problems:(1) Less arable land per capita and low level of intensive land use;(2) the regional differences in land use are large;(3)the proportion of construction land occupying cultivated land is too large;(4) the expansion speed of construction land is too fast.
