| 摘 要： | 目前干旱区突出的矛盾是,人类活动对环境的负效应在总体上已导致以土地荒漠化急剧发展为主的生态环境质量显著下降。基于1994年“联合国防治荒漠化公约”给出的土地荒漠化概念和干旱区的特点,划分土地荒漠化的自然因素和人为因素。通过人类活动的涵义和特点的探讨,首次全面和综合地分析了土地荒漠化发展中的人类活动因素,包括人类活动的驱动作用、人类各种活动方式的作用和人类活动的管理作用等。依据一定的原则,构建出适用于干旱区人类活动对土地荒漠化作用的指标体系,该指标体系多为量化指标并可反映人类活动的动态变化,可为人类活动在土地荒漠化中作用的更进一步(定量)研究提供依据。

| Abstract: | Currently,one of the important conflicts in arid areas is the negative impact of human activities to environment,which results in the obvious degeneration of ecological environment dominated by land desertification. In this paper,the natural and human factors resulting in land desertification are compartmentalized based on the conception of land desertification described in the "United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and /or Desertification,Particularly in Africa,October 1994 in Paris" and the general features in arid areas. By discussing the meanings and characteristics of human activities,the human factors,such as the driving effects,ways and management functions of human activities in the development of land desertification,are synthetically analyzed. According to some principles,the index system of human activities resulting in land desertification in arid areas is developed,the index system includes some quantitative indexes of human activities,can reflect the dynamic change of human activities,and can provide the basis for further studying the effects of human activities in land desertification. |
