【摘要】 根据气候相关模型计算了西双版纳自然植被净第一性生产力(NPP),结果表明:在一定的土壤和植被生物学特性的情况下,西双版纳自然植被净第一性生产力随年总辐射、年降水量的变化而变化,其中年降水量是决定该地区NPP大小的主要因子,而西双版纳由于地理位置纬度较低,属于热带地区,1960～1999年40年间年平均温度变化较小,对本地NPP的影响较弱.另外,通过粮食产量与NPP的比较分析,得知西双版纳地区自然资源的可利用潜力仍十分丰富,具有较大的发展潜力.更多还原

【Abstract】 Using the Chikugo model of the climatic relative Model Calculated the net primary productivity (NPP) of natural vegetation in Xishuangbanna.The result indicates that NPP of natural vegetation in Xishuangbanna vary with the variation of the annual radiate and the annual rainfall on certain condition that the soil character and the vegetation ecology character.The annual precipitation is most important factor that decide NPP in Xishuangbanna.During 1960～1999,the annual mean temperature varied less in Xishuangbanna,which hardly influence the variation of NPP in the region.In addition,comparing NPP with the foodstuff yield,the conclusion can be got as a follow:The natural resource is very abundant,having more the potential productivity in Xishuangbanna.更多还原
