【摘要】 通过对不同植被类型的土壤和枯落物水分储量的计量与评价分析,认为近20年来九寨沟自然保护区植被生态水总储量的变化呈增加趋势,且林地生态水储量占各时段生态水总量的比例均较大,表明国家各项林业生态建设与保护工程的实施起到了积极的作用。今后应继续加大各项工程的建设力度,进一步提高区内植被生态水的储量,为世界自然遗产的保护、利用和发展奠定坚实的基础。更多还原

【Abstract】 The water storage of the soil and litter from different vegetations in Jiuzhaigou region were estimated and assessed.The results showed that the total eco-water storage tended to increase in the short space of twenty years.Due to the implementation of the various ecological construction and protection projects in forestry,the ratio of the eco-water storage of forestland to the total eco-water storage was already high in different times.Thus,the various construction and protection projects should be further implemented so as to elevate the eco-water storage in Jiuzhaigou region to facilitate the protection,utilization and development of the world natural heritage.更多还原
