摘要
石漠化地区立地分类及其植被恢复潜力评价是石漠化地区生态修复的重要基础,立地因子研究是立地分类与评价的前提。通过对典型强度石漠化地区毕节石桥小流域和花江峡谷立地条件调查,利用成因分析与统计分析方法,研究强度石漠化地区影响植被恢复潜力的主要立地因子。结果表明:岩性和坡性是强度石漠化地区基于植被恢复潜力的主导立地因子。研究结果可为强度石漠化地区立地分类的建立与植被恢复潜力评价提供依据。
Site classification and vegetation restoration potential evaluation are important for ecology restoration in rock desertification area.Studying on site factors is a basis for site classification and site evaluation.Through fields investigation of site conditions in Shiqiao catchment of Bijie and Huajiang valley,which are typical serious rock desertification areas,using the methods of causative analysis and statistics analysis,the key site factors of serious rock desertification area have been studied.Results show that the rock character and slope character are controlling site factors of serious rock desertification area based on vegetation restoration,which will provide the foundation for site classification and evaluation in the serious rock desertification region.
