摘要
采用农业生物多样性评价方法 ,对汉龙社集体林 4个植被样方调查 (其中 2个为监测样方 ) ,共有 90个植物物种出现在调查样方中 ,其中农业物种 63个 ,占物种总数的 70 %。两个监测样地显示 ,由于长期无限度的砍伐 ,汉龙集体林植物物种多样性逐年降低 ,植株个体数量和质量也逐年降低。由于林业权属不稳定和缺少有效的保护措施 ,导致集体林管理混乱 ,使集体林遭到越来越严重的破坏。文中探讨了社区森林有效保护和发展的方法和途径。
Ninety plant species are recorded in four sampling plots of community forests by using vegetation sampling method and agrobiodiversity assessment method of PLEC BAG guidelines. Sixty three plant species are managed species, which occupy 70% of total species in sample plots, used for medicines, timbers, fuel wood, fodders, wild fruits, wild vegetables and industry oils. The results of two monitoring sampling plots indicate that plant species diversity and arbor numbers and timber volume are decreasing becaus...
