Analysis of Spatial Pattern Changes of Cultivated Land Resource in Jianghan Plain
基于地理信息图谱和马尔可夫转移矩阵，分析了1980-2010年江汉平原耕地与水域、建设用地间的转换规律及区域差异，对生态保护有参考价值。
The research is conducted based on the geographic information tupu analytic method and Markov analysis and transfer matrices. Using this method, the paper has made the tupu analysis of evolution of spatial pattern of cultivated land resources in Jianghan plain between 1980 and 2010.With the support of tupu analysis method, this paper also has measured the regional difference of dynamic of cultivated land with the research area counties. The result shows that,during 1980 to 1990, the led type of regional land transfer was conversion of arable land to water. On the contrary,during1990 and 2000, the main characteristic of cultivated land change was that the main added cultivated land resources were from water. During 2000 to 2010 the led type of regional land transfer was conversion of arable land and construction land. During the 30 years period, the dynamic of cultivated land, in the eastern research area had increased obviously. While in the western research area, the dynamics of cultivated land had been decreased gradually. Studies suggest that Jianghan plain is an eco- landscape system which dominated by cultivated land and water. So, scientific response to their relationships plays a vital role for the whole region ecological protection.
