莫索湾一五○团农场绿洲生态环境的基本情况及其保护

150团农场是一个经过人工改造、加工,并受人类支配的绿洲生态系统。它位于天山北侧,准噶尔盆地西南缘,莫索湾垦区的西北隅。1958年建场,至今仅30余年,也是该垦区深入古尔班通古特沙漠最深远的一个年轻人工绿洲。由于所处地理环境、发展历史及生态分布格局,这片绿洲有其本身的特点,也有准噶尔盆地南部沙漠边缘一些人工绿洲的许多共同之处,因此研究其生态环境,对认识沙漠边缘绿洲的特点,存在问题,制订绿洲的保护和建设的战略,均具有一定的理论价值和实际意义。

The Main Characteristics of Oasis Ecotope and Its Protection in the Farm of 150th Corps

Being well-developed in forest network and relatively stable in ecosystem,the farm in 150th corps,a new man-made oasis established in the background of desert ecosystem, is a typical irrigation agriculture. Anyhow, it is deficient in the source of water and getsa vile climate. Besides, the boundary line contacting with the sandy desert ecosystem around the farm is quite long.Thus, it is in the serious threat of desertification.Preventing the intrusion of harmful matter in sandy desert ecosystem into oasis, protecting the sandy vegetation in the periphery of the oasis, constructing the Blue Ecologic Project in the contacting belt of oasis with desert and fully utilizing the resources of sunlight,heat and water are the important way to bring the ecologic function of oasis ecosystem into fullplay.
