云南怒江峡谷民居与森林资源可持续利用

在云南怒江峡谷贡山和福贡2县,通过对传统民居结构和材料的调查,将民居按屋顶、墙体和地板进行分类的基础上;对其中主要民居类型的民用材消耗量及民居结构导致的薪材消耗量进行了估算,表明传统民居的用材选择和建筑结构是决定当地森林资源消耗方式和数量的主导因素。因此,在科学保护传统民居文化的前提下,通过推广节材民居类型,改良现有建筑结构,降低民用材和薪材消耗;同时加强集体林、自留山森林资源管理,增加森林蓄积量,最终实现森林资源可持续利用。

Traditional dwellings and sustainable utility of forest resources in Nujiang Valley of Yunnan Province

In Gongshan and Fugong counties of Nujiang Valley, the structure and material of traditional dwellings were investigated, after which the basic classification was made according to the roof, wall and floor of traditional dwellings. The timber requirement of major traditional dwellings and fuelwood consumption resulting from their poor warm-keeping capability were estimated. It was found that the traditional dwelling was a key factor determining the pattern and quantity of forest resources consumption in Nujiang Valley. On the premise of scientifically protecting traditional dwellings, it was concluded that forest resources consumption would be decreased through improving the structure of existing dwellings and promoting timber-saving ones. On the other hand, forest growth stock should be increased through strengthening collective and household forest management, so as to reach the goal of sustainable utility of forest resources.
