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。
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.
