现代生物多样性的迅速丧失主要是由于对土地的不合理利用所致,因此对土地的合理利用被认为是生物多样性有效保护的基础。西双版纳是我国植物多样性最丰富的地区之一,然而,由于土地利用的变化,植物多样性也不同程度受到影响。为探讨土地利用对生物多样性的影响,本文在样方调查的基础上,运用定量的方法计算西双版纳主要的土地利用方式对生物多样性的影响指数(I=1/E,E=log10(v3ser))进行计算,发现对植物多样性的影响依次为:单一的橡胶种植园、橡胶+茶叶、橡胶+菠萝、家庭庭园、寺庙庭园、天然林下砂仁的种植、丢荒(8年)的轮歇地、集体林、龙山林和保护区。因此,要有效保护西双版纳的生物多样性,一是要保护好现存的自然保护区与传统信仰林,二是在土地开发利用时要推广既有较好的经济和社会效益,同时又有较好的生态效益的混农林技术。
The rapid loss of modern biodiversity is mainly due to the irrational use of land, and therefore the rational use of land is considered to be the basis for the effective protection of biodiversity. Xishuangbanna is one of the most abundant plant species in our country. However, due to the change of land use, plant diversity is affected to varying degrees. In order to explore the impact of land use on biodiversity, based on the sample survey, this paper uses the quantitative method to calculate the influence index of biodiversity on the main land use patterns in Xishuangbanna (I = 1 / E, E = log10 (v3ser )), And found that the impact on plant diversity were as follows: a single rubber plantation, rubber + tea, rubber + pineapple, family gardens, temple gardens, Amomum villosum plantation, abandonment of famine (8 years) Turns, collective forest, Longshan forest and protected areas. Therefore, to effectively protect biodiversity in Xishuangbanna, one is to preserve existing nature reserves and traditional belief forests. The other is to promote good economic and social benefits both in land development and utilization and at the same time, The ecological benefits of agroforestry techniques.
