Study on the soil hydro-structure function of restored vegetations in the Yunnan Shilin park of China

School of tourist and geographic sciences, Yunnan Normal University

摘要

摘要: 基于喀斯特恢复植被生态系统功能评价的要求，采用土壤水文结构功能模型评价云南石林景区恢复植被的土壤水文结构功能。选取原生滇青冈林、恢复26a的次生林B、恢复21a次生林A、恢复8a的灌丛、石漠化灌草丛和恢复30a云南松林6个样地，分别调查它们的土壤水文结构特征。相对于原生林，石漠化样地经过8a的封禁，其土壤水文结构功能可恢复31%，21a可恢复45%，人工飞播的云南松林经过30a恢复的只有38%，而砍伐林地封禁26a可恢复71%。土壤水文结构功能评价模型基本适用于岩溶区不同恢复林地的土壤水文结构功能的恢复评价。

Abstract: Based on the requirement of ecosystem function assessment of restored vegetations in karst area, the soil hydro-structures function of restored vegetations were evaluated by the soil hydro-structure function model in the famous Shilin park in Yunnan province of China, which is a part of south China karst world natural heritage. Six vegetation sample plots, which form a succession of restored vegetations in the karst area ,including original forest (forest of Cyclobalanopsis glaucoides), 26 years secondary forest B (secondary forest of Cyclobalanopsis glaucoides), 21 years secondary forest A (secondary forest of Neolitsea homilantha) , 8 years brush, rock-desertification bushy grasses and 30 years secondary forest of Pinus yunanesnis, were chosen for assessment. As contrasted with the original forest, 31% of soil hydro-structure function can be restored after ecology recover and blockading administer for 8 years, and 45% can be restored after 21 years of ecology recovery in rocky desertification plots. And only 38% in secondary forest of Pinus yunnanensis can be restored after 30 years of ecology recovery, while 71% of soil hydro-structure function can recover after 26 years of eco-closing .The model of soil hydro-structure function is basically suitable for evaluation of restored vegetations in karst areas.
