我国松嫩平原中部,多为以碱草为建群种的草地,是发展畜牧业的重要基地之一。这里盐渍土面积达90％以上,主要是由于气候干旱、过渡放牧与不合理的采草等原因所致,从而造成土壤盐渍化程度加重,碱斑面积扩大,草原退化,草质变劣,产草量和载畜量明显降低。据在大庆红色草原牧场一分场调查,每年采草时期机械压地面积达43％;重度盐渍化土壤面积约占一半左右;植被组成中碱草比重逐年减少,而盐蒿和碱蓬增加;放牧场上碱斑面
China’s central part of the Songnen Plain, mostly for sage grass for the construction of the grass is an important base for the development of animal husbandry. The area of saline soil is more than 90%, mainly due to arid climate, transitional grazing and irrational grass-mining, which lead to the increase of soil salinization, the increase of alkali spot area, the deterioration of grassland, the deterioration of grass quality, Yields and stocking were significantly reduced. According to the investigation of the Daqing Red Prairie Ranch, the area under mechanical pressure during the harvesting period reaches 43% each year; the area of heavily salinized soils accounts for about half; the proportion of Siberian herb and grass in the vegetation decreases year by year, while that of Artemisia halophyte and Suaeda salsa increase Alkali stains in grazing land
