采用Ｃ语言和Ｆｏｘｐｒｏ数据库，根据Ｂｒｏｏｋｓ和Ｃｏｒｅｙ，Ｇｅｎｕｃｈｔｅｎ的土壤水分特征曲线模型，编制成《土壤水分特征曲线拟合软件》，用该软件完成了北京林业大学妙峰山林场土壤水分特征曲线的拟合及其图形与数据文本的制作，并分析了该地土壤的水分特性．结果表明，采用土壤水分特征曲线上－１．５ＭＰａ下的含水量近似代替残留含水量与从水分特征曲线拟合得到的残留含水量相比差异较大；采用Ｂｒｏｏｋｓ和Ｃｏｒｅｙ模型拟合的土壤水分特征曲线，相关指数均在０．９９以上；所有试验地之间，水分特征数据无显著差异．
Using C language and Foxpro database, according to Brooks and Corey, Genuchten soil moisture characteristic curve model, compiled “soil water characteristic curve fitting software”, using the software to complete the Beijing Forestry University Miaofengshan forest soil water characteristic curve fitting And its graphics and data text production, and analysis of the soil water characteristics. The results showed that the variation of water content at -1.5MPa on the soil moisture characteristic curve was similar to that of the residual water content, which was significantly different from the residual water content obtained from the fitting of water characteristic curve. The soil moisture, which was fitted by Brooks and Corey models, The characteristic curves and correlation indices are all above 0.99. There is no significant difference in water characteristics between all test sites.
