摘要
以武汉市作为研究区域,对1996-2012年的土地利用结构变化进行分析。首先将城市化与土地利用各结构类型进行灰色关联度分析,寻找其中的内在联系;然后对武汉市土地利用各结构类型的变化率和变化幅度进行比较分析;最后建模分析武汉市土地利用各结构类型的综合利用程度。结果表明,武汉市近年土地综合利用程度呈上升趋势,但建设用地面积增长过快,与城市化关联度高;而耕地面积大量减少,与城市化关联度小,这样的城市化发展是不可持续的。就此提出要保护耕地,控制建设用地面积的增加,提高建设用地利用率的建议。
We take Wuhan as the study area to analyze the change of its land use structure from 1996 to 2012. First of all, we use grey relational analysis to find out the relationship between the urbanization of Wuhan and the types of its land use structure. Then we compare the vary rate with the vary breadth of each sort of land. Finally, we construct a model to analyze the degree of the overall land use of Wuhan. The research shows that in recent years the degree of overall land use of Wuhan displayed upward trend. The construction land grew fast and had high degree of association with the urbanization. Meanwhile, cultivated land area decreased rapidly showing little degree of association with the urbanization. This development of urbanization is not a sustainable type, so we make suggestions that it should be necessary to protect arable land, control the increase of construction land and enhance the utility rate of construction land.
