采用地统计学方法和Lattice Wombling界面判定方法对典型农牧交错带(河北沽源地区)农田-草地景观镶嵌体土壤水分界面的瞬时界面因子空间特征进行初探.结果表明:利用地统计学对不同粒度的土壤水分空间特征研究验证土壤水分界面存在,且存在不同生态梯度效应.应用Lattice Wombling界面判定方法对农田-草地界面土壤水分进行界面的瞬时判定表明,农田-草地界面土壤水分界面的判定呈不规则曲线的界面变化;农田-草地界面土壤水分界面的界面因子(BE)在农田内部较为明显,在距农田草地边界农田一侧的3~7 m处和草地内部3 m处左右.
Geostatistics method and Lattice Wombling interface determination method were used to investigate the temporal characteristics of instantaneous interfacial factors of soil-moisture interface in farmland-grassland landscape mosaic in a typical farming-pastoral ecotone (Guyuan, Hebei Province). The results show that using geostatistics for different The study on the spatial characteristics of soil moisture at grain-size showed that the soil-water interface existed and had different ecological gradient effects. The instantaneous determination of the interface of soil moisture at farmland-grassland interface using Lattice Wombling method showed that the determination of soil- The interfacial factor (BE) at the soil-water interface of farmland-grassland interface is more obvious in farmland, which is about 3 ~ 7 m on the farmland side and 3 m inside the grassland on the farmland border.
