物元可拓模型在雁江区土壤养分综合评价中的应用
The Application of Matter-element Extension Model in Yanjiang Soil Nutrient Comprehensive Evaluation
摘要
Abstract
By using geo-statistics and GIS spatial analysis technology,soil nutrients of Yanjiang Region in Sichuan Province was evaluated with the application of matter-element extension model.pH,organic matter,total nitrogen,rapid available phosphorus,available potassium were selected as soil nutrients evaluating indexes.The evaluating result is accord with the actual situation.Matter-element model can eliminate the effect of artificial factors in evaluation process.At the same time, it is an ideal model of increasing yield and stability to improve the evaluating precision.It is one of the most important methods to grasp the fertilization principle upon the mscroscopic in a certain range, which analyze the srade of soil nu-trient and construct comprehensive evaluation model to definite the level of the fertility of soil.关键词
