摘要: 运用Miami模型、Thornthwaite模型以及综合模型,计算浙江省植被NPP,并与国际生物学计划(IBP)推荐值进行比较,旨在找出最适用于浙江省的一种植被NPP计算模型;分别分析三种模型模拟的植被NPP的年际及年代际变化特征;利用站点的经纬度、DEM及其衍生数据建立多元回归方程对浙江省植被NPP进行空间插值,并分析其空间分布特点。结果显示:(1)综合模型模拟的浙江省植被NPP与国际生物学计划(IBP)推荐值最接近,为952.722~1376.971g.m-2.a-1,并且NPP随时间呈波动上升趋势;20世纪60-70年代植被NPP增幅最大,为33.31g.m-2.a-1;(2)对于三种模型,北部嘉兴市的植被NPP最小,南部温州市的植被NPP最大;植被NPP的空间分布形态一致,全省范围内均表现为西北低、东南高;(3)比较得出,综合模型在模拟计算浙江省NPP时更具有实用性。

Abstract: Using Miami model,Thornthwaite model and Comprehensive model,NPP in Zhejiang Province was calculated to find an optimal model through comparing the calculating results with the values by IBP recommended. Then,the characters of annual and decadal NPP were analyzed. Based on the multiplex regression equation,the NPP was carried out spatial interpolation with longitude,latitude,DEM and its derived data. And spatial distribution of NPP was investigated. The results showed that (1) the calculation of comprehensive model was between 952.722 and 1376.971g m-2 per year,which was most close to the recommended values,and NPP wavelike ascended with time. (2) For the three NPP models,the maximum appeared in Jiaxing of the north and the minimum value appeared in Wenzhou of the south. NPP's spatial distribution of the three models all showed that the lower value appeared in northwest and the higher appeared in southeast. (3)Comprehensive model were more feasible to calculate NPP of Zhejiang Province.
