| 摘 要： | 选取2000和2007年两个时期的TM数据,利用基于NDVI的像元二分模型,估算佛山市的植被覆盖度,并分析其时空变化的情况.结果 表明,近8年来,佛山市的植被覆盖度总体上呈下降的趋势,并存在区域间不平衡的现象.较高植被覆盖区的面积减少了384.41 km2,变化率为27.26%,而较低植被覆盖区的面积和中度植被覆盖区的...

| Abstract: | The landsat TM data in 2000 and 2007 are selected to estimate and analyze the change of vegetation coverage in Foshan by using the dimidiate pixel model based on NDVI.The results show that the vegetation coverage in Foshan decreased in the past 8 years and the changes in different districts were different from each other.The area of highly vegetation-covered decreased by 384.41 km2 with a change rate of 27.26% while that of mildly and moderately vegetation-covered increased by 80.55 km2 with a change rate o... |
