摘要: 基于富互联网应用(RIA)方法,利用C#语言和IDL语言混合编程技术,将全国MODIS NDVI遥感产品数据、气象和植被等数据作为模型输入参数,设计并开发出基于RIA技术的中国植被净初级生产力在线估算与查询系统。该系统可以实现中国植被净初级生产力在线查询、影像在线估算、统计、专题图制作、出图以及用户管理等多项功能,可满足用户对我国植被净初级生产力估算、查询等的需求。

Abstract: As the driving force of the carbon cycle, net primary productivity(NPP)is not only one of basic quantitative characteristics in earth’s ecosystems, but also the main factor to determine the carbon source, sink and the regulation of ecological processes. Based on RIA technology, normalized differential vegetation index(NDVI)of MODIS, meteorological and vegetation data of China were collected as input parameters of CASA, an online estimation and query system of vegetation net primary productivity of China(EQSVNC)was developed for the first time to full in the blank of web-platform of NPP query and estimation in China. The EQSVNC took advantage of the C# language and IDL language, and achieved the following functions: online query, estimation, statistics, export of mapping and printing thematic map of Chinese vegetation net primary productivity, and management of users. The EQSVNC not only can conveniently and effectively meet many users’ demands for estimating and querying Chinese vegetation net primary productivity, but also provide a scientific data-sharing web-platform for scientific researchers and policy makers.
