二、前言焉耆盆地是东天山中一个山間盆地,具有一般山间盆地的水文地貭規律。由于它不是完全封閉的盆地,且海拔較高(1000—1200米),在地貭地貌条件綜合控制之下,它的水文地貭規律与吐魯番、哈密等十分密閉的、海拔很低的盆地有很大的区别。現根据我們1958年7月的調查资料,和新疆水利厅开都河流域勘測队的資料,对控制盆地区域水文地貭条件的自然地理因素及地貭背景,和盆地一般的水文地貭規律作初步的論証,在这个基础上对地下水的利用等方面作出实际的建議。二、自然地理概况与地貭环境焉耆盆地是东段天山偏南部的一个山間盆地,位于东經85°10′—87°30′、北緯42°23′—41°40′的范围內,东西长約125公里、南北最大寬度62.5公里,成西北狹东南寬的楔形。
II. Preface The Yanqi Basin is a mountain basin in the East Tianshan Mountains. It has the laws of hydrology in the general mountain basins. Because it is not a completely enclosed basin and has a high altitude (1000-1200 m), under the comprehensive control of terrain and geomorphology, its hydrological regime is very close to that of Turpan and Hami. Great difference. Based on the survey data from July 1958 and the data from the Kaidu River Basin Investigation Team of the Xinjiang Water Resources Office, we analyze the natural and geographical factors that control the hydrological conditions in the basin and the background of the meso-megalopolis, The initial argument, on this basis, make practical suggestions on the utilization of groundwater. 2. Overview of Geographical Geography and Terrestrial Environment The Yanqi Basin is a mountain basin located in the southern part of the Tianshan Mountains in the eastern segment of the basin. It lies between 85 ° 10’-87 ° 30’E and 42 ° 23’-41 ° 40’N, About 125 km long, the maximum width of 62.5 km north-south, into a narrow westerly southeastern narrow wedge.
