利用遥感手段对省级自然保护区人类活动监测技术进行探讨,形成了人类活动遥感监测技术路线、技术指标、数据处理方法、关键参数等成果;并提出了省级自然保护区人类活动遥感监测方法。以太安省级自然保护区为例进行示范研究,结果表明,影像分辨率应以5 m为主、2 m为辅;2015年该保护区人类活动包括农业用地、居民点、工矿用地、采石场、道路和其他人工设施6类,占保护区总面积的17.08%;人类活动类型以农业用地为主,占人类活动总面积的86.49%;人类活动主要分布在实验区,但有采石场位于核心区;2013～2015年面积减少最多的为林地,同时农业用地面积增加最多;保护区人类活动影响指数为0.001 217,核心区受人类活动影响大,不利于该地区的生态系统保护。

In this paper, we discussed the monitoring technologies on human activity of provincial nature reserve in Shaanxi Province by RS, which formed the technical route, index, data processing method and key parameters of human activity. On the basis of this, we built the monitoring methods accordingly. Taking Tai'an provincial nature reserve for example, the results show that the image of 5 m resolution should be used first, and then 2 m. There are agricultural land, residential, mining land, quarry, road and other artificial facilities in the nature reserve, which accounts for 17.08% of the total area in 2015. The main human activity type is agricultural land, which area accounts for 86.49% of the total area of human activity. Most of the human activities distribute in experimental area, but there are quarries located in the core area. The area of forest land reduces, and most of the reduced area changed into agricultural land, road and residential from 2013 to 2015. The human activity index of the reserve is 0.001 217 in 2015, and the core area is greatly influenced by human activities, which is not conducive to the ecosystem protection of the reserve.
