公路路基的合理高度是保證沙漠公路不產生沙害的主要因素之一,同時是提高沙漠地區公路等級的關鍵,沙漠公路路基填土高度低,則易出現沙埋病害,路基受沙漠地基穩定狀況及地下水的影響顯著,反之,則易出現風蝕病害,並存在高填方路基和穩定性問題,工程造價相應增加。According to the idiographic complexion of our country, the article elucidated the connotation of conservation tillage : it ' s a technology of tillage with minimum tillage or no - tillage so as to reduce the soil ' s disturbing, using stalk cover the field so as to decrease laboring and tillage ' s cost, preventing wind & water erosion, and improving the fertility of soil and the ability of fight a drought
摘要根據保護性耕作在我國的實施情況並結合國外已有研究結果,我們認為保護性耕作的內涵為:保護性耕作措施就是對農田實行少耕或免耕,盡可能減少對土壤的擾動,並以秸稈覆蓋地表,達到減少勞動強度和生產投入,防止農田風蝕和水蝕並提高土壤肥力和抗旱能力的一種農田耕作技術。The gullies are formed by the processes of infiltration - interflow - collapses. ( 2 ) in the slope with sand - loess, the major factors of water erosion are the rainfall intensity and rainfall amount of annual first rainfall.
