crusting soil
解釋
結皮土-
Bare soil is protected from the impact of rainfall which can cause surface soil crusting, compaction, and erosion
塑料薄膜覆蓋使裸土免受降雨引起的表土結殼、壓實和侵蝕。 -
Through rainfall simulating under laboratory, and making slice of sampling, the project researched in the soil crust development, and studied the dynamic rule of erosion factors which were raining and soil erosion factors during soil crust development. in the same time, the research was to find the critical condition of all factors in the process of soil crusting, and to filter the critical factor that could affect soil surface crust
本文採用人工模擬降雨方法，通過采樣製作土壤切片，觀察分析表土結皮在不同條件下發育的微形態特徵，研究降雨、土壤等侵蝕產沙因子在表土結皮發育過程中的動態響應規律，界定表土結皮發育過程中各因子的臨界條件，篩選有關土壤顆粒組成、結構特徵等物理化學性質對表土結皮形成影響的關鍵因子。 -
Factors which influence field soil water infiltration characteristics have soil structure, soil moisture, soil texture, topsoil crusting and plate, agriculture husbandry measure and soil water phase change and so on
影響大田土壤水分入滲特性的因素有：土壤結構、土壤含水量、土壤質地、表土結皮和板結、農業耕作措施和土壤水的相變等。 -
The aim of this research was to confirm the rule of soil crusting and the factors affecting the process of soil crusting, and to analyze the relationship between the development of soil crust and rainfall splash erosion, furthermore to study the effect of soil crust on the process of erosion. we hope to provide scientific bases for soil erosion
本研究的主要目的是探明表土結皮的發育規律、影響因子，並且分析表土結皮的形成與土壤濺蝕的關系，以及表土結皮的發育與坡面侵蝕過程的交互動態影響作用，最終為坡面侵蝕研究提供科學依據。 -
Scanning electric microscope ( sem ) photographs were used to examine the structure of surface soil experienced a rainstorm, for the purpose of understanding the mechanism of soil crusting. it approved that soil crusting consists of depositional crust and structural crust. the curves of infiltration with time revealed four stages of crust formation
用電子掃描顯微鏡（ sem ）照片對比了土壤表面結構，分析了土壤的結皮機理，可以認為土壤結皮是由結構結皮和沉積結皮構成，入滲量與時間的歷時曲線反映了結皮的四個形成過程。
