Soil is the base of agriculture production, the key measure to prevent water and soil loss is to conserve soil, but most soil nutrient is lost with the sediment loss, and serious water and soil loss make the soil thickness degrease, the soil nutrient be deficient and lean, the land quality degrade and the yield of plant decrease, all this results is going to threaten the people ' s transplanting and the agriculture sustainable development, and restrict the economy development of three gorges regions
同時，土壤是農業生產的根本，治理水土流失的關鍵是要保住土壤，而土壤養分絕大部分是隨著泥沙流失的，嚴重的水土流失造成土層淺簿、養分貧瘠，土地質量退化，產量下降，對三峽庫區移民工作和農業可持續發展造成嚴重威脅，制約三峽庫區經濟發展。因此進行三峽庫區坡耕地土壤侵蝕機理研究，探索減輕坡耕地土壤流失的方法措施，具有全局性的重大意義。In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints, this thesis made com land, fallow land, orchard, grass land as experimental field in black soil region jlau, which carried out experiment by applying different amounts of n and p fertilization in corn field. by means of collecting the samples of rainfall runoff, erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field, we study the effect of surface runoff on n and p nutrient and fertility degeneration. the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p, in which rainfall and rainfall intensity were more important, while rainfall intensity is the most important meteorological phenomena factor
針對當前黑土利用現狀，本文借鑒眾多學者的研究方法和觀點，在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地，在玉米區進行了不同數量的施肥，通過野外試驗，採集一年自然降雨產流及泥沙樣品，同時採集降雨前後的耕層土壤樣品，研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響，結果表明：土壤侵蝕和氮磷的流失受諸多因素的影響，降雨量、降雨強度是重要因子，而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子，特別是暴雨，暴雨徑流中氮磷濃度較平時高得多；隨作物生長，覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異，氮磷流失都表現為顯著的差異。Ancient farmers developed several methods to farm the desert.
古代農民發展了在沙漠耕作的幾種方法。So elijah went from there and found elisha son of shaphat
19於是，以利亞離開那裡走了，遇見沙法的兒子以利沙耕地。Through the dome runoff sediment deposition trial in three experiment stations including ningcheng, helin, dongsheng in inner mongolia, using the way of data analyzing, whether the relationship of representative influencing factor of soil erosion and the amount of soil erosion of sloping farm land in loess hilly in inner mongolia during once rainfall is exist and how much is the degree of correlation
摘要通過對內蒙古寧城、和林、東勝三個試驗站進行坡面徑流泥沙試驗，採用數據分析法，研究內蒙古黃土丘陵區坡耕地在一次降雨中各典型影響因子與土壤侵蝕量之間是否存在相關關系及相關程度問題。The social and economic impact caused by the construction of plover cove reservoir were not just confined to the nearby villages. the ancillary works, including water pipelines and access roads, reached out to areas as far as sai kung, yuen long, castle peak, tsuen wan and sha tin. some rivers in these areas were diverted making agricultural pursuits difficult, as residents needed to obtain fresh water from outside their villages. some villages were turned into new roads, with residents being forced to resettle elsewhere
船灣淡水湖於1961年春開始興建工程，不但影響附近的村落，水塘的配套工程如興建輸水管和修築公路等，波及范圍遠至西貢、元朗以北、青山、荃灣及沙田一帶，有些鄉村因原有河道被堵截而無法再從事農耕，生活飲用水亦需外求，有些鄉村被辟為公路，整條鄉村被迫遷徙。分享友人
