【摘要】：礦產(chǎn)資源的開采容易導(dǎo)致礦區(qū)土地資源破壞及生態(tài)環(huán)境惡化,為探索煤礦開采對土壤侵蝕的影響,分析礦區(qū)土地侵蝕狀況。以貴州省西南部煤礦城市六盤水市為研究對象,基于土壤質(zhì)地、地形、氣候、土地覆蓋和土地利用等數(shù)據(jù),運(yùn)用RUSLE模型,結(jié)合GIS空間分析方法,研究六盤水市土壤侵蝕現(xiàn)狀及空間分布特征,著重分析煤礦區(qū)土壤侵蝕分布特征。結(jié)果表明:(1)六盤水市土壤侵蝕以微度、中度侵蝕為主,侵蝕嚴(yán)重區(qū)域主要集中在水城縣東部和南部,六枝特區(qū)東部以及盤縣中部。(2)土壤侵蝕主要發(fā)生在人類負(fù)向干擾活動強(qiáng)烈的林地、草地、旱地、煤礦區(qū)和裸地。(3)六盤水市南部煤礦區(qū)侵蝕較嚴(yán)重,以中度侵蝕為主,主要原因是采煤造成的地質(zhì)災(zāi)害使土壤侵蝕抑制因素作用減弱。(4)私營煤礦區(qū)土壤侵蝕程度比國有煤礦區(qū)嚴(yán)重。私營煤礦區(qū)應(yīng)在煤炭開采過程中加強(qiáng)保護(hù)與治理。
[Abstract]:The exploitation of mineral resources can easily lead to the destruction of land resources and the deterioration of ecological environment in mining areas. In order to explore the influence of coal mining on soil erosion, the situation of land erosion in mining areas is analyzed. Based on the data of soil texture, topography, climate, land cover and land use in Liupanshui City, a coal mine city in southwestern Guizhou Province, this paper applies RUSLE model and GIS spatial analysis method. The present situation and spatial distribution of soil erosion in Liupanshui City were studied, and the distribution characteristics of soil erosion in coal mining area were analyzed. The results show that the soil erosion in Liupanshui is mainly slight and moderate erosion, and the serious erosion area is mainly in the east and south of Shuicheng County. Soil erosion occurred mainly in woodland, grassland, dryland, coal mining area and bare land in the eastern part of Liuzhi Special Zone and in the central part of Panxian.) the main erosion was moderate erosion in the southern coal mining area of Liupanshui City. The main reason is that the geological disaster caused by coal mining weakens the function of soil erosion inhibition factor. 4) the degree of soil erosion in private coal mining area is more serious than that in state-owned coal mine area. Private coal mining areas should be strengthened in the process of coal mining protection and governance.
