- 摘要:
- 基于GIS技术和遥感数据，监测了武川县2000—2020年的土地利用数据和植被覆盖度变化情况;同时，基于植被净初级生产力评估研究区植被生长水平，以期掌握研究区植被生态环境变化。结果表明：2000—2020年，武川县主要土地类型为草地和农田，分别占研究区总面积的64.50%~74.76%和20.86%~31.61%；武川县平均植被覆盖度呈逐年增加状态。从2000—2020年，武川县中等、较高等和高等植被覆盖度分别增加了4.23、6.20、5.37倍，而低等和较低等植被覆盖度分别减少了15.34、2.89倍。武川县东部植被覆盖度显著高于西部地区，南部边缘处植被生长状况较好。武川县年均植被NPP为176.10~290.93 Cg·m-2，整体呈现先下降后上升的趋势，东部地区植被NPP明显优于西部地区。总体而言，武川县2020年草地资源明显好转，但仍需要注重生态环境的保护，大力发展民族特色旅游，改善武川县的生态环境问题。
- Abstract:
- Monitoring changes in grassland resources is beneficial for protecting grassland resources and ecological environment.Based on GIS technology and remote sensing data，the land use data and changes in vegetation cover in Wuchuan County from 2000 to 2020 were monitored in this study.At the same time, the level of vegetation growth in the study area was evaluated based on the net primary productivity of vegetation,in order to capture the changes in the ecological environment of grassland resources in the study area.The results showed that the main land types in Wuchuan County from 2000 to 2020 were grassland and farmland，accounting for 64.50%-74.76% and 20.86%-31.61% of the total area of the study area，respectively；the average vegetation cover in Wuchuan County was increasing year by year.From 2000 to 2020，medium，more and higher vegetation cover in Wuchuan County increased by 4.23，6.20 and 5.37 times，respectively，whereas lower and lesser vegetation cover decreased by 15.34 and 2.89 times，respectively.Vegetation cover was significantly higher in eastern Wuchuan County than in western areas，and vegetation growth was better along the southern edge.The average annual vegetation NPP was 176.10-290.93 Cg·m-2 in Wuchuan County，showed an overall trend of first decreasing and then increasing.The vegetation NPP in the eastern region was significantly better than that in the western region.In general，the grassland resources of Wuchuan County in 2020 had significantly improved，but it is still need to focus on the protection of the ecological environment，vigorously develop tourism with ethnic characteristics，and improve the ecological environment problems in Wuchuan County.
