| 摘 要： | 我国西南喀斯特地区存在着以石漠化为表现形式的土地退化过程,以景观生态学及生态经济学原理为基础,寻求人类活动与自然协调的景观生态安全格局,无疑是实现石漠化土地持续利用的一条重要途径。石漠化土地可持续利用景观生态规划是基于格局优化的目标规划和基于干扰分析的问题规划的结合,并借鉴预案研究的方法和思路。首先确定退化土地安全层次和总体规划目标,提出多种预案进行评价比较,最终要落实到实施措施的空间定位。以桂花河流域石漠化土地可持续利用景观生态规划为例进行了初步研究,通过分析桂花河小流域石漠化土地在不同土地利用类型和不同坡度中的分布,提出优先治理的几种预案,综合比较得出6类土地生态修复和可持续利用模式和各项工程的空间布置。希望能为西南喀斯特地区的石漠化土地综合防治提供有益的参考。

| Abstract: | The degradation land of karst rocky desertification is one of the most serious problems on economic development, eco-system restoration and reconstruction in southwest China. It is an important approach to realize sustainable use for rocky desertification land to seek the landscape pattern for ecological security based on the principles of landscape ecology and ecological economics. Furthermore, landscape eco-planning of sustainable use for rocky desertification land integrates the relevant two kinds of ecological planning approaches, the Pattern optimization and the disturbance management according to the features of regional ecological and environmental problems and human disturbances, and uses the scenarios study for reference. First, determine the security level and planning goal, suggests some scenarios for further comparisons, and determine the spatial layout of the measures in the end. For an example, several preferential fathering scenarios have been put forward by analyzing the distribution of rocky desertification land under different land use types and gradients at Guihuahe small watershed, then 6 kinds ecological rehabilitation and sustainable use models have been suggested by integrated comparation. The preliminary study on landscape planning of sustainable use for rocky desertification land at Guihuahe small watershed might be a help for the rocky desertification land comprehensive prevention and restoration of southwest China karst region. |
