摘要
据最新调查数据,云南省石漠化草原主要分布于曲靖、昆明、红河等 5 个州(市),总面积37.97 万hm2,占岩溶土地面积的 3.53%,其分布最广的海拔区间为 1 500～2 500 m,占比 47.85%,基岩裸露度分布区间为30%～94%,以植被盖度为 10%～19%的分布区间面积最广,占比 37.85%,绝大部分分布于土层薄甚至极薄区域,占比达 92.10%.根据石漠化草原空间分布特征,在充分衔接各大生态保护和修复工程建设规划基础上,统筹考虑岩溶生态系统的完整性、地理单元的连续性和经济社会发展的可持续性,将云南省石漠化草原区划为6 个分区,分区阐述石漠化草原生态保护与修复策略.
Abstract
According to the latest survey data,the rocky desertification grassland in Yunnan Province is mainly distributed in five regions including Qujing City,Kunming City and Honghe Prefecture,with a to-tal area of 379700 hm2,accounting for 3.53%of the karst areas.The widest distribution range was from 1 500 to 2500 meters above sea level,accounting for 47.85%,and the distribution range of bedrock ex-posure was 30%to 94%.The distribution range with vegetation coverage of 10%to 19%was the widest,accounting for 37.85%,with the vast majority distributed in areas with thin or even extremely thin soil layers,accounting for 92.10%.Based on the spatial distribution characteristics of rocky desertification grasslands,and fully connecting with the construction plans of various ecological protection and restora-tion projects,taking into account the integrity of karst ecosystems,the continuity of geographical units,and the sustainability of economic and social development,the distribution of rocky desertification grass-lands in Yunnan Province was divided into six zones,and the ecological protection and restoration strate-gies of rocky desertification grasslands were elaborated in each zone.
