发达地区土地利用结构变化定量分析——以浙江省慈溪市为例
|
摘要
以经济发达的浙江省慈溪市为研究区域,运用计量地理模型和信息熵等研究方法,探讨了该市土地利用类型、土地利用综合程度、地类区位指数和土地利用结构信息熵等.结果表明:(1)慈溪市部分镇的土地利用结构受地形地貌的影响较大,一些镇和街道的土地利用类型不完备,个别镇和街道的城镇村及工矿用地的比例过大,未来耕地被挤占的可能性非常大.(2)慈溪市土地利用的多样化状况在总体上处于中等水平,而且各镇(街道)之间的差异并不大.各镇(街道)的土地利用集中化程度普遍较低.全市土地利用类型齐全程度整体上偏低.(3)慈溪市土地利用程度综合水平相对较高,各镇(街道)的土地利用程度与区位、地形地貌、经济发展水平和产业结构等因素有关.各镇(街道)的土地利用类型在优势度和均衡度上差异较大.(4)慈溪市土地利用结构的影响因素主要包括:地形地貌、经济发展水平、城市化特征和产业结构等,它们对土地利用结构的影响机制差异较大.
Taking the developed Cixi city of Zhejiang province as the example area,the land use types,comprehensive degrees of land use,location indexes of land use,and the information entropies of land use structures were explored by using a research method of quantitative geography model combined with information entropy. The results showed that:( 1) the land use structure of some towns in Cixi city was strongly affected by the topography,while the land use type of some towns and streets was not complete. The proportions of urban village,industrial,and mining land in some towns were too large,thus the possibility of cultivated land be squeezed was very large in the future;( 2) generally speaking,the diversification of the land usage in Cixi city was in the middle level,and the difference among different towns was not big. The centralization degree of all towns was somehow low,and the overall level of land usage types in the whole city was low too;( 3) the comprehensive degree of land usage in Cixi city was relatively high. The comprehensive degree of each town was contributed by its location,topography,the level of economic development,industrial structure and so on. The dominance and equilibrium of land use type of all towns were quite different;( 4) the influencing factors of land use structure in Cixi city were mainly contributed by: topography,the level of economic development,the characteristics of urbanization and industrial structure,etc. Their influence mechanism on land use structure was totally different.
