云南干热河谷植被与环境研究进展

特殊的地理位置和独特的地形地貌特征组合形成了典型的干热气候环境,在云南省亚热带高原山地河谷下部发育了一类特有的植被类型,即干热河谷植被。干热河谷植被具有非地带性和稀有性,以及由土地利用变化为主的人为活动干扰导致的脆弱性。本文回顾了干热河谷植被的研究历史,分别从干热河谷的植物群落学和植物区系学、干热河谷植被与土地的关系以及干热河谷植被保护与恢复三个方面进行了总结。植物群落与区系研究主要集中于群落分类、植被分类、群落特征、人为干扰影响、区系特征、性质和起源;植被与土地关系研究侧重于土壤特性、土地利用/覆盖变化、土地退化及水土流失状况;植被保护与恢复的热点在植被恢复目标、植被恢复功能区划、植被恢复引...

Summary:特殊的地理位置和独特的地形地貌特征组合形成了典型的干热气候环境,在云南省亚热带高原山地河谷下部发育了一类特有的植被类型,即干热河谷植被。干热河谷植被具有非地带性和稀有性,以及由土地利用变化为主的人为活动干扰导致的脆弱性。本文回顾了干热河谷植被的研究历史,分别从干热河谷的植物群落学和植物区系学、干热河谷植被与土地的关系以及干热河谷植被保护与恢复三个方面进行了总结。植物群落与区系研究主要集中于群落分类、植被分类、群落特征、人为干扰影响、区系特征、性质和起源;植被与土地关系研究侧重于土壤特性、土地利用/覆盖变化、土地退化及水土流失状况;植被保护与恢复的热点在植被恢复目标、植被恢复功能区划、植被恢复引种及筛选及植被恢复效益评价研究。未来在这些区域应注重自然灾害及预防、水电工程建设对植被的影响及其响应等方面的研究,深入开展大尺度植被时空格局的监测和动态服务功能分析。
Bibliography:The vegetation of the dry-hot valleys in southwestern China, especially in Yunnan, is unique as the valley bottom in a subtropical plateau and mountainous region, which is characterized by its geographic location, climate, and geomorphology. A long history of biological adaptation to the specific environmental contributes to the rarity and non-zonality of vegetation in these dry-hot valleys. Disturbances including land use through human activities have endangered some vegetation types in the dry-hot valleys. This paper examines the history of vegetation studies in the dry-hot valleys, and summarizes studies on flora, vegetation and land use and cover change, as well as vegetation restoration. Research of plant communities and flora have mainly focused on the classification of the community and vegetation types, the characteristics of the community, the influence of human disturbance, and the characteristics, nature and origin of the flora. The relationship between vegetation and land has mainly focused on the
