| 摘 要： | 净初级生产力是生态系统碳汇、生态系统调节过程的主要因子之一,对生态系统碳汇的研究具有重要意义。本文以黑龙江省的13个地区气象观测站1952-2012年的气象数据（包括平均降水量、平均温度、陆地表面所获得的净辐射量等）为数据源,以Miami、Thornthwaite、Chikugo和朱志辉4个模型分别计算黑龙江省植被初级生产力（NPP）值。同时,采用富客户端技术（RIA）,构建黑龙江省植被NPP碳汇分析系统。该系统可实现地图基本操作功能、查询分析、统计分析、NPP值渲染和在线计算NPP值等功能,实现了资源和信息的共享,可为政府决策部门提供一种可视化、操作便利、直观反映结果和友好交互式的决策辅助工具。

| Abstract: | Net primary productivity is one of the main factors to determine ecosystem carbon and ecological adjusting process, which has vital significance to the research of ecosystem carbon. Taking the meteorological data of 13 meteorological stations during 1952- 2012 in Heilongjiang Province as data resources,the NPP values were calculated by using Miami,Thornthwaite,Chikugo, and Zhu Zhihui models. Meanwhile,the carbon analysis system of vegetation net primary productivity of Heilongjiang Province was established by using RIA technology. The system had the following functions： basic operation,query analyst,statistics analyst,NPP values coloring,online caulation of NPP values,and so on. Thus,the sharing of resources and information would be realized,which provides a decision- making and accessory tool for visualization,convenient operation,and reflecting intuitional NPP results. |
