土壤风蚀中有关土壤性质因子的研究历史与动向

RESEARCH HISTORY AND TREND ON SOIL PROPERTY FACTORS CONCERNING WIND EROSION

国外土壤风蚀中有关土壤性质因子的研究历史可分为四个阶段：第一，定性描述阶段；第二，定量实验研究阶段；第三，运用综合因子建立和完善“通用风蚀方程式”阶段；第四，土壤风蚀土壤亚模型和预测系统的建立和动态研究阶段。国内对土壤风蚀的研究起步较晚，对于不同土类的土壤物理化学性质对风蚀的影响尚没有作深入研究。其历史大致可分为二个阶段：第一，野外观测研究；第二，风蚀的半定量实验研究。目前正由半定量向定量化、标准化、国际化以及动态研究方向发展。

Research history abroad on soil properties about wind erosion can be divided into four stages. The first stage is characterized by wind erosion phenomenon discription. The second is quantitative research stage by experiments. The third is characterized by applying varied factors to set up Wind Erosion Equation and its improvement. The fourth is setting up sub soil model prediction system. Wind erosion research history on soil properties inhome can be divided into two stages. The first is field observation research stage. The second is semi quantitative research stage. At present, wind erosion research on soil properties are developing toward quantification, standardization and internationaliza tion.
