准噶尔盆地南缘扇缘带的土地利用

Land Utilization at the Edge Belt of Alluval Fans in the Southern-Fringe of Junggar Basin

准噶尔盆地南缘光热和土地资源极为丰富，目前绿洲外线广阔土地由于受到水资源。十地质量及其它条件的限制．多供放牧之用。根据在扇缘带设点进行的作物生态适应性和经济效益的分析及土壤改良利用试验，认为建立适度面积的高产人工草地，以草料作物苜蓿、玉米的种植为主，贯彻以牧为土，农牧结合的方法是扇缘带土地利用的最佳途径。

Southern-fringe of Junggar basin is rich in light,heat and land resource.A vast of lands around outside of Oases have been mainly used for rangeland due to the restriction of water resource,land quality and among others.According to the analyses of ecological suitability and ecomic benefit of crop,and the experiment of soil utilization and amelioration from the trial on these lands,the best ways of using the land are to open a moderate amount of area for high yeild artificial grassland with alflafa and maize the forage as the main crops,and to take the animal husbandry as the dominant industry with farming as combination.
