摘　　要：基于地理信息系统和遥感技术对恒山风景区2000—2010年生态系统功能的变化进行研究,结果表明:景区的土地利用变化主要是生态用地向非生态用地的转化;景区的植被覆盖度、植被净初级生产力、水源涵养能力及土壤保持能力均有所下降。分析其原因主要是由于旅游开发和周边采矿引起,而植被净初级生产力在一定程度上也受到气象因素的影响。The change in ecosystem functions of Hengshan Scenic Spot Area from 2000 to 2010 was studied by means of geographic information system （GIS） and remote sensing （RS） technology. The results showed that the major change in land use during the 10 years was that the land for ecological purpose was converted to non-ecologi- cal purpose. The vegetation coverage, the net primary productivity of the vegetation, the water retention and soil conservation capacities of the scenic spot area were all decreased. The main reasons to cause the above change in- cluded the development of tourism and mining, whereas the reduction of the net primary productivity of the vegeta- tion in this area was partially caused by the meteorological factors.
