不同等级石漠化综合治理的小气候效应-以贵州省花江峡谷为例
摘要： 对贵州省花江峡谷区12个石漠化样地小气候进行观测和研究.结果表明,随着石漠化综合治理时间延长,植被结构得到改善,小气候效应逐渐凸现:不同等级石漠化样地林下平均气温及土壤温度在湿热季节得到有效降低,而在干冷季节略显升高;空气相对湿度在年际同期水平显著提高;林下光照强度逐渐减弱.生态系统结构的改善,使得系统开放性降低,能量散失减少,生态环境朝着良性有序方向发展. Abstract： In this paper microclimate was observed and studied in 12 plots under different rocky desertification degrees in the Huajiang Gorge Area of Guizhou. Results showed that architecture of vegetation and effects of microclimate have been improved with changing comprehensive treatment time: air temperature and soil temperature fall efficaciously in wet-hot season but have been improved appreciably in dry-cold season. Relative air humidity is improved obviously with the same season in different years. Intensity of illumination tends to weaken bit by bit. Ecosystem structure that has been improved efficaciously makes openness of the ecosystem to fall and energy to lessen. Quality and function of the entironment have been improved in a proper way. 作 者： 吴克华 熊康宁 李坡 龙明忠 曲明昕 WU Ke-hua XIONG Kang-ning LI Po LONG Ming-zhong QU Ming-xin 作者单位： 吴克华,李坡,WU Ke-hua,LI Po(贵州科学院喀斯特资源环境与发展研究中心,贵阳,550001)熊康宁,XIONG Kang-ning(贵州师范大学中国南方喀斯特研究院,贵阳,550001)
