石漠化整治地学模式探讨

The Research on Geoscience Modelfor Stony Desertification Renovating

石漠化实质是在喀斯特地质环境条件下人类需求与资源承载力矛盾的结果。因此,石漠化的治理必须“防”、“治”结合,“标”“本”兼治,才能达到最佳效果。本文在分析石漠化形成和发展实质的基础上从预防的角度提出了石漠化整治的地学基本模式,阐述了地学模式建立的基本思想、模式基本特征及内涵、模式实施的途径。模式立足于提高资源的承载力、协调资源的供需矛盾,与其他生态修复模式配合,将对喀斯特山区石漠化的综合整治起到积极的作用。

Stony desertification is actually resulted from the contradiction between requirements of human being and resources - carrying abilities of the karst - geologic settings. So we must give attention to both the“prevention” and “control”, to a “temporary solution” and the “permanent cure” in the renovating of it, that the best effects can be achieved. In the light of essential consideration on the forming and developing essence of stony desertification, aiming at its prevention, a basic geoscience model for the renovating of stony desertification is offered; the fundamental ideas of establishing the model, its basic feature and implied meaning, and the implementary path are also exposited. Established on the basis of heightening the resources - carrying capacity and harmonizing the contradiction between supply and demand of resources, combining with other models of ecologic restoration, this model may play an active role for synthetic renovation of the stony desertification in the karst mountain areas.
