摘要
选取高程、坡度、年均温、年降水、年均相对湿度、土地利用、植被指数等7个因子,利用RS、GIS相关的分析技术,对大冶湖流域历年景观生态进行综合评价.研究结果表明,大冶湖流域景观质量总体偏低,但随时间推移不断好转;景观质量呈现偏正态分布,结构较稳定;大冶湖流域景观质量南部地区高于北部地区,南北差异明显,大冶湖周边地区景观质量较差;大冶湖流域景观的多样性较低,均一性程度较高,呈现不断扩大的趋势.
Selecting seven factors in total of elevation, slope, annual average temperature, annual precipitation, annual average relative humidity, land use, vegetation index and using RS, GIS analysis technology, a comprehensive evaluation about the landscape ecological of the Daye lake basin was made each year. The conclusion is as follows: The quality of Daye lake basin is on the low side, but it gets better as time goes by; The landscape quality is normal distribution, and the structure is stable; the landscape quality in southern is higher than the north, the differences is apparent, and the landscape which surround Daye lake area is low; The diversity of landscape is low, the degree of homogeneity is high and shows a trend of increasing.
