岩溶区生态恢复与重建的初步效果及意义

Primary effects and significance of ecological rehabilitation and reconstruction in karst terrains.

介绍了中国-斯洛文尼亚科技合作项目《利用有益动物繁殖系统进行岩溶地区的休养再生示范》实施的背景与岩溶区生态恢复重建的思路。通过试验,已找到桂北岩溶区适生的优良牧草和灌木品种。研究发现,这些品种对岩溶区的物种多样性、生态级别、土壤养分、土壤特性、土壤水涵养性等均有明显的改善作用,为中国南方岩溶区生态恢复与重建提供了科学依据。

This paper introduces the background of the implementation of the Sino-Slovenia scientific and technological cooperative project ＂Demonstration of Rehabilitation of Karst Terrains by Introducing an Environmental Friendly System of Breeding Useful Animals＂ and the idea of ecological rehabilitation and reconstruction in karst regions. After tests, some fine species of forage grasses and shrubs that are suitable for the growth in the karst terrain of Guilin have been found. It is apparent that these species can improve the species diversity, ecological grading and soil nutrients, properties and moisture. This study provides an important scientific basis for the ecological rehabilitation and reconstruction in karst regions of southern China.
