随着经济的发展,人类活动直接或间接地改变着土地利用方式和土地覆被结构,进而改变水资源分配,影响了绿洲内部的生态环境和过程。策勒绿洲土地资源丰富,光照充足,但是水土资源利用不平衡,可利用的水资源量并不多,可用水的缺乏造成土地的开荒—撂荒—开荒的反复,使得策勒绿洲耕地面积波动较大。日益膨胀的绿洲过度耗水,进一步影响到绿洲外围山区水源区环境,造成荒漠水分不足,影响植被生长。通过对农业水土资源利用的研究,简析了水土平衡的重要意义,为策勒绿洲水土资源合理开发利用提供依据。图1,表4,参3。
With economic development, human activities directly or indirectly change the land use patterns and land cover structure, thereby changing the distribution of water resources and affecting the ecological environment and process within the oasis. Cele oasis rich in natural resources, adequate light, but the imbalance in the use of water and land resources, available water is not much, the lack of water caused land reclamation - abandonment - wasteland reclamation, making Cele oasis cultivated area fluctuations Big. The overexploitation of oasis water will further affect the environment of water source areas in mountainous areas surrounding the oasis, resulting in the shortage of desert water and affecting the growth of vegetation. Through the study of the utilization of agricultural land and water resources, this paper analyzes the significance of soil and water balance and provides the basis for rational exploitation and utilization of land and water resources in Cele Oasis.
