摘要:
宁夏地处西北，干旱少雨，植被稀少，是我国生态环境十分脆弱的地区。基于MODIS NDVI数据，利用像元二分模型估算宁夏地区2000—2016年的植被覆盖度，并定量分析其植被覆盖景观格局变化及发展趋势，为宁夏地区生态环境建设提供科学依据。研究表明：2000—2016年，宁夏植被覆盖整体向良好方向发展，呈现极低植被→低植被→中植被→高植被覆盖转移趋势，高植被覆盖有向中植被覆盖转移，但转移比例较小；农田植被区高植被覆盖程度不断增强，自然植被区极低植被与低值被覆盖占全区面积的70%以上，且低值被覆盖有向极低值被覆盖转移的情况，生态环境建设不容懈怠。
Abstract:
Ningxia is located in the northwest China, where the climate is dry and the vegetation is scarce, the ecological environment is very fragile. Based on MODIS NDVI, the vegetation coverage of Ningxia from 2000 to 2016 was estimated by using the binary model, and the changes and development trend of vegetation cover landscape pattern were quantitatively analyzed in order to provide scientific basis for the construction of ecological environment in Ningxia. The results showed that:the vegetation cover in Ningxia was developing in a good direction from 2000 to 2016, showing a very low vegetation → low vegetation → medium vegetation → high vegetation cover transfer trend, high vegetation had a transfer to the medium vegetation cover, but the transfer ratio was low, and the coverage of high vegetation in farmland vegetation area was increasing. In the natural vegetation area, very low vegetation and low value covered more than 70% of the total area, and low vegetation had a transfer to the very low vegetation cover, the ecological environment construction can not be slacked.
