分宜县土地细碎化的中观尺度研究

研究目的:借鉴土地格局领域的研究思路,在中观尺度上研究土地细碎化,以期在研究方法、数据获取等方面寻求突破,并利用2004年分宜县遥感影像解译的土地利用矢量对10个乡镇土地利用细碎化进行研究。研究方法:文献资料法,景观格局指数法,聚类分析法。研究结果:在中观尺度上研究土地细碎化问题,得到与微观尺度研究截然不同的结论——低山区土地细碎化程度最低,其次是平原区,而丘陵区的土地破碎化程度最高。研究结论:分宜县各乡镇土地利用细碎度指标的聚类结果空间分布规律特征十分显著。

Research on Land Fragmentation of Fenyi County on Meso-level

The purposes of this paper are firstly to examine land fragmentation on meso-level in order to achieve some new findings in research methods and data acquisition, which is referred from the idea of land pattern, and secondly to study the land fragmentation problems of ten townships in Fenyi County via the land-use vector interpreted from the remote sensing images in 2004. Methods of documentary data, landscape pattern index and cluster analysis are employed. The results indicate that there is an entirely different assessment result between the meso-level and the micro-scale on the issues of land fragmentation, i.e., on meso-level the land fragmentation degree of low mountain area is the lowest, the plain area is the second lowest, and the hilly area is the highest. It is concluded that the characteristics with spatial distribution trend from the cluster results of the land-use fragmentation indices in every township in Fenyi County are extremely remarkable.
