黑龙江省生态系统碳储量空间插值及分析系统的研究

Study On The Spatial Interpolation And Analysis Ecosystem Of Carbon Storage In Heilongjiang Province

本文以黑龙江省为研究区域,以固定样地的生态系统(包括乔木、灌木、草本、枯枝、枯叶、半分解层)碳储量为数据源,采用Arc GIS10.0平台的反距离权重法(IDW)、样条插值法(Spline)、克里金插值(Kriging)三种空间数据插值方法,通过每种不同的方法设置不同的参数,得到针对不同插值方法的相关成果,并把数据点分成70%的训练样本和30%的测试样本,应用SPSS对结果的数据进行对比分析,得出结论反距离权重插值法拟合情况较好。之后,通过应用软件dreamviewer构建B/S模式以进行研究成果的发布,主要模块包括:信息发布模块、信息查询模块、系统管理模块。

Taking Heilongjiang province as an example, the carbon storage of fixed sample of ecological system （ including trees, shrubs, grasses, twigs, leaves, semi -decomposed layer） as the data source, using ArcGIS 10. 0 platform of the inverse distance weighting method （ IDW）, spline interpolation method （ spline）, Kerry （ and three kinds of spatial data interpolation method, through Kriging） each kind of different method to set different parameters according to different interpolation methods of relevant results, and the data points are divided into 70% of the training samples and 30% of the test sample, the application of SPSS to the results of data analysis, draw the conclusion of inverse distance weighted interpolation method to fit better. After that, through the application of the software dreamviewer to build the B/S model to carry out research results, the main modules include： information release module, information query module.
