摘要
以湖北省蕲春县印度IRS P6遥感影像为信息源,以ArcGIS 9.2以及ENVI为空间地理数据处理平台提取该县土地利用类型信息,对蕲春县景观格局进行定量分析研究。结果表明:该县景观多样性较高,斑块类型丰富,但分布不均。具体表现为:针叶林面积最大,为优势景观;河流、湖泊和水库成大面积连片聚集状态分布;灌木林、阔叶林、无林地、水域分布零散;其它(主要为村镇建设用地)斑块数量最多,斑块面积小且分散。
In this study,basic geographic data coming from Indian IRS-P6 remote sensing images of Qichun county in Hubei province were analyzed by ArcGIS 9.2 processing platform to obtain this coutry land use information.Based on this information sources,landscape patterns in Qichun were discussed quantitatively in this article.The rusults showed that the landscape diversity was at a high level.The patch types were abundant and uneven.The concrete analysis was made as follows： The largest area was coniferous forest.The distribution of rivers,lakes and reservoirs was concentring in a continuous mode.The patten of shrubbery,broad-leaved forest,non-forest land and other water area were scattered.The other land types,mainly including the construction land of towns and villages,were in the largest numbers,but their areas were small and scattered.
