鄱阳湖滨不同植被类型沙地土壤有效持水能力研究
|
摘要
鄱阳湖滨沙地是我国南方典型的沙地。研究采用经过筛选的土壤转换函数(PTFs)比较分析了鄱阳湖滨沙地4种主要植被类型(刺槐、湿地松、蔓荆子和自然荒草地植被)土壤的有效持水量,旨在为南方湖滨沙地生态植被恢复提供土壤水分评价方法参考,也为更好地评价不同植被类型的沙地生态恢复模式效应提供依据。结果表明:通过统计检验,Rawls模型的ME和RMSE值分别为0.005 8,0.001 0,显示其较Saxton模型、Batjes模型、Minasny模型具有更好的预测准确度,更适合于鄱阳湖滨沙地土壤水分特征估算分析;经过测定表明,不同植被类型土壤田间持水量依次为湿地松>蔓荆子>刺槐>荒草地;Rawls模型计算结果表明:不同植被类型土壤凋萎系数依次为刺槐>湿地松>蔓荆子>荒草地,不同植被类型土壤有效持水量依次为湿地松>蔓荆子>刺槐>荒草地。
Sandy soil of Poyang Lake is located in the south of China. Available water holding capacity of the sandy soil in four different plantation types was analyzed with method of pedotransfer functions. The results showed that ME and RMSE of Rawls model were 0.005 8 and 0.001 0, respectively, suggesting that Rawls model exhibited the higher projection accuracy, and was much fitter for estimating available soil water holding capacity of sandy soil in Poyang Lake region than Saxton model, Batjes model and Minasny model; the soil field capacity under different types of vegetation decreased in the order: Pinus elliotii>Fructus viticis>Robinia pseucdoacacia>natural grass; according to the values estimated by Rawls model, the permanent wilting point of soil under different types of vegetation decreased in the sequence: Robinia pseucdoacacia>Pinus elliotii>Fructus viticis>natural grass, the available water holding capacity of soil decreased in the order: Pinus elliotii>Fructus viticis>Robinia pseucdoacacia> natural grasst.
