元江县磨房河水库库区植被恢复研究

Vegetation restoration in Mofanghe reservoir zone of Yuanjiang County

以元江县磨房河水库库区植被恢复为对象,分析了库区植被恢复的重要性和必要性,指出通过划定自然保护区、实施工程造林及搬迁库区人口等措施,库区的森林覆盖率提高了89.2%,森林土壤的涵水能力大大加强,库区泥沙淤积明显减少,取得一定的生态和社会效益。针对当前库区植被恢复所面临的投资大、见效慢、经济与生态不相协调、造林树种单一等问题,提出今后应加强库区综合开发工作,重视乡土树种的利用,大力推广造林新技术,以促进库区植被恢复的有效开展。

The present study was conducted to analyze the importance and necessity of vegetation restoration in reservoir zone through investigating the vegetation restoration in Mofanghe reservoir zone of Yuanjiang County. According to the present situations of Mofanghe reservoir zone, some measures including division on natural reserve into various zones and forestation, migrating population and so on, were conducted to increase the forest coverage with 89.2%, strengthen the water holding capacity of soils in forest, and reduce sediment siltation in reservoir zone. At present, there exist some problems in vegetation restoration of reservoir zone which inculde heavy investment, slow effect, discoordination between economy and ecology, use of single tree species for forestation, etc. Therefore, it has been suggested that the comprehensive development of reservoir zone should be strengthened, the indigenous tree species should be utilized, and new forestation technologies should be extended vigorously to improve the sustainable development in vegetation restoration in reservoir zone.
