基于遥感更新的省级生物丰度归一化系数研究——以湖北省为例

Study on Normalized Coefficient of Provincial Organism Abundance Based on RS Data Updating: Hubei Province as an Example

在中国资源环境数据库三期数据支撑下,利用2005年TM影像对湖北省土地利用信息的数据遥感更新,计算出1995年和2000年两个时期的湖北省省级生物丰度归一化系数,并对不同尺度的归一化系数进行分析和研究.绘制出1995年、2000年湖北省生物丰度等级图,清晰反映出湖北省生物丰度的区域分异规律,为我国生态环境影响评价研究提供技术支持.

Supported by the three periodic data of Chinese Resources and Environment Data- base, at the meantime updating the remote sensing data of land use information in Hubei province using the 2005 TM image, to calculate the provincial normalized coefficient of the year of 1995, 2000 in Hubei province and study on different scales of normalized coefficients. Meanwhile draws the map of Hubei organism abundance rating, clearly reflects the regional difference of organism abundance in Hubei, in order to provide technical support for eco-environment assessment in China.
