| 摘 要： | 根据水土环境中盐渍成分时空分异的区域化特征，提出盐渍水土化学场理论，建立变异函数模型定量化模拟其空间分异，求得变异函数后，通过克立格插值定量化预测某种盐渍水土环境特征的空间分布。利用在松嫩平原盐渍化试验小区的实测数据进行验证，可为盐渍水土环境的定量化研究提供理论依据。 |
| 关 键 词： | 松嫩平原 盐渍化 水土化学场 变异函数 克立格插值 空间分布 |

| Abstract: | According to regional distribution characteristics of salt in water-soil environment, the theories of Salt Distribution Field in Water-Soil Environment are put forward. Variation function offered is used to model quantitatively space differentiation of salt in water-soil environment, and its space distribution can be modeled quantitatively by Kriging interposing method offered. At last, this method is applied by integrating experimental data in saline soil of Songnen Plain, and get EC sample variance map in paddy field and saline badlands, at the same time, get different direction EC sample variance and soil EC Kriging interposing isoline in paddy and saline badland. This theories can be used quantificationally study on saline and alkaline water-soil environment. |
