摘要:
基于江苏省2000和2005年2期森林资源清查数据,在分析其森林资源结构特征基础上,采用生物量换算因子连续函数法,对森林生物量和生产力进行了估算,分别从龄组、优势树种、区域等方面进行了对比分析。结果表明:江苏省森林生物量由2000年的6 783.23 万t 增加到2005年的8 633.19万t,森林净生产力也由1 623.68万t·a-1上升到2 092.50万t·a-1; 平均生物量从53.20 t·hm-2减少到41.18 t·hm-2,平均生产力由10.55 t·hm-2·a-1减少到9.90 t·hm-2·a-1,即森林资源总量不断增加,平均量有所下降,这可能与幼、中龄林在森林净生产力所占比重较大有关。其次,利用geoda0.95i软件对江苏省森林生物量进行了空间分布格局分析表明,江苏省森林生物量(林分、经济林、竹林)的全局自相关指数I为0.264 7,经Z检验存在空间正自相关,空间呈现显著的聚集特征。
Abstract:
Based on the data from the forest inventories(CFI)in 2000 and 2005,the forest biomass and net primary production(NPP)in Jiangsu Province were estimated by the variable biomass expansion factor function(BEFF)method which derived from the relationship between biomass and volume. Meanwhile,they were comparatively analyzed from age group,dominant species,and area,etc. From 2000 to 2005,the total biomass increased from 67.83 to 86.33 million tons,and each hectare of the total NPP increased from 16.24 to 20.92 million tons per year; the average biomass per hectare decreased from 53.20 to 41.18 tons per year; and the average NPP per hectare decreased from 10.55 to 9.90 tons per year,indicating that the total amount of forest resources increased,while the average amount declined.This may be related to the young and mid-maturation which accounted for a large proportion in the forest net productivity.The results of the analysis carried out by the geoda0.95i software demonstrated that the global autocorrelation index(I)of forest biomass(stands,non-timber forests,and bamboo)was 0.264 7,and the biomass presented positive spatial autocorrelation,featuring a significant accumulation characteristics after Z test.
