【摘要】 茂兰喀斯特森林是地球亚热带地区保存最完好、面积最大的喀斯特森林生态系统。喀斯特森林凋落物作为生态系统的重要组成部分和森林物质能量循环的的载体,有非常重要的生态学意义。喀斯特森林凋落物不仅是森林物质能量循环的基础,是重要的碳汇,还对森林土壤的物理性状、化学性质、土壤生物等产生重大影响,是喀斯特森林水土保持、加速喀斯特作用的重要基础。石漠化的关键是植被的破坏、地被物的消失导致生态过程中断。更多还原

【Abstract】 Maolan karst forest is one of the biggest areas and best condition conservation on the earth in subtropical karst forest ecosystem.Karst forest litter ecosystem has very important ecological significance in that component of ecosystem and cycle of forest energy carrier material.Karst forest litter material energy is not only the basis of forest,important carbon sink,also the physical properties of forest soils,biological and other chemical properties of soil have significant effect,karst forest soil and water conservation is an important basis.Rocky desertification is the key to the destruction of vegetation has been the disappearance of plants,resulted in disruption of ecological processes.更多还原
