四川秦巴山区植被覆盖变化及其影响因素分析OA
Analysis of vegetation cover change and its influencing factors of Qinba Mountains in Sichuan Province
四川秦巴山区是重要的生态与水源涵养保护地,区内植被覆盖水平高,但生态环境脆弱且复杂,明确该区域植被覆盖变化情况及其影响因素,有利于为区域生态保护和植被恢复提供科学依据,为维持区域生态安全提供保障.基于MODIS-NDVI数据,利用像元二分法估算四川秦巴山区 2001～2020年植被覆盖度,通过线性趋势法、Hurst指数、重心迁移模型、最优参数地理探测器等方法分析其时空变化、景观格局及影响因素.结果如下:①2001～2020年,四川秦巴山区植被覆盖…查看全部>>
The Qinba Mountains in Sichuan Province is an important ecological and water conservation protection area,with high vegetation coverage,but fragile and complex environment.A clear understanding of the changes of vegetation coverage and its influencing factors in this area is conducive to providing scientific basis for regional ecological protection and vegetation restoration,and providing guarantee for maintaining regional ecological security.Based on MODIS-…查看全部>>
