- 摘要:
- 及时、准确地获取植被覆盖信息是矿区生态恢复和建设的关键与重点,现选用七台河市1993、2000、2011年3期的TM卫星数据,使用ENVI遥感软件提取归一化植被指数(NDVI),根据像元二分法计算七台河市的植被覆盖度,利用Isodata分类方法对七台河市的植被覆盖度进行分等定级,最后得出七台河市1993~2011年的植被覆盖度分类图,定量说明该区域近20年间的植被覆盖变化情况。1993~2000年,植被覆盖度下降比较明显,2000~2011年植被覆盖有所上升,但仍未达到1993年水平。
- Abstract:
- Timely and accurately access to information on vegetation cover is the key to ecological restoration and construction of the mine.Selecting Qitaihe city 1993,2000,2011 three TM satellite data,using the ENVI remote sensing software to extract the normalized difference vegetation index(NDVI),calculating vegetation coverage according to pixel dichotomy in Qitaihe city,using Isodata classification,Qitaihe vegetation coverage was classified and graded.It came to conclude Qitaihe city of 1993 to 2011 vegetation cover classification map,quantitative described the vegetation cover changes in the region for nearly 20 years.It showed that from 1993 to 2000,the vegetation coverage decreased evidently,from 2000 to 2011,the vegetation cover increased,but had not reached the 1993 level yet.
