| 摘要: |
| 利用土壤侵蚀强度的变化程度代表生态环境的变化，根据土壤侵蚀强度减轻与加剧情况，把生态环境划分为明显改善、轻微改善、基本未变、轻微加剧及严重加剧五个等级，对研究区5年间的生态环境演变概况进行分析。并利用近50多年来的气象、社会经济和遥感监测等资料，分析了气候变化和人类活动对麻地沟地区生态环境的影响。结果表明：气候变化和人类活动对生态环境都会产生显著的影响，当前麻地沟地区的生态环境状况是气候变化和人类活动共同作用的体现。 |

| Abstract: |
| Using the change of soil erosion intensity level to represent the ecological environment change, according to the reduction and aggravation situation of soil erosion intensity, the ecological environment is divided into obvious improve, slight improve, basically not changed, slight aggravation and serious aggravation. And the paper analyzed the ecological environment situation of study area for 5 years evolution. Using meteorology, social economy and remote sensing monitor data in nearly more than 50 years, this paper analyzed the influence of climatic change and human activities on the ecological environment in Madigou area. The results show that climate change and human activities will have a significant effect on the ecological environment, and the current ecological environment conditions of Madigou area is the concurrent embodiment of climate change and human activities. |
| Key words: ecological environment climatic change humanity activities Madigou area |
