植穴微宇宙控制技术对盐渍土水盐运移的调控作用

在分析国内外有关盐渍土水盐运移规律研究的基础上，提出一种全新的植穴微宇宙控制技术对盐渍土水盐运移的调控法。文章从微宇宙控制技术的理念出发，以局部植穴微生态的调控方式，将生态结构的主导因子，即生物与其相适应的非生物环境条件为控制要素，在不同的微宇宙结构（植物、无机基质、边缘材料等）和自然因子（地下水矿化度、土壤质地、补水量等）条件下，运用混合均匀设计U12（12×4^4×3^4），建立人为控制的植穴微宇宙结构和自然因子与水盐动态变化之间的相关数学模型．探求植穴微宇宙在盐土中对水盐运动的调控机理．意在解决局部植穴内微生态系统的平衡与稳定．以点带面推动植穴微宇宙的汇向源斑块的转移．以植穴微宇宙的规模效益实现生态逆境的可持续生态修复。

Regulating Effect of Controlling Technology of Microcosm of Plant Hole on Water-salt Transport of Saline Soil

After analyzing concerned researches of water-salt transporting rule of saline soil at home and abroad, the paper suggested a bran-new method of the regulating effect of controlling technology of microcosm of plant hole on water-salt transport of saline soil On the basis of the concept of microcosmic controlling technology, with the regulative and controlling mode of microecology of local plant hole, making the leading factor of ecological structure, which are the biology and compatible abiotic environment condition as the controlling factor, on the condition of different microcosmic structure （the plant, inorganic substrate, fringe material, etc） and natural factors （the mineralization of groundwater, soil texture, water replenishment, etc）, applying the hybrid uniformity design U12 （12×44×34）, the author established a correlated mathematical model among artificial controlling microcosmic structure of plant hole, natural factors and water-salt dynamic variation and searched after regulating mechanism of microcosm of plant hole on water-salt transport in the saline soil, in order to resolve balance and stabilization of microecology of local plant hole and drive patch transfer of microcosm of plant hole. Microcosm of plant hole of scale benefit could realize sustainable ecological restoration of ecological adversity.
