Since the success of the test of drip irrigation under membrane technology in Shihezi City in 1996,the drip irrigation technology has been rapidly applied and extended in Xinjiang. Then it was extended to the oasis in arid areas such as Gansu and Qinghai. In addition to that the related experiments were carried out in the oasis of Central Asia. In the context of the Belt and Road Initiative,it is necessary to comprehensively analyze the suitability of application and promotion of drip irrigation in different types of oasis in the arid area of Central Asia based on such experiments and extensions in Kazakhstan,Kyrghyzstan,Tajikistan and so on. Since drip irrigation technology can save water resource as well as improve production of crops,meanwhile,it can also ease the harm of salinization and protect the environment,which has great potential to be extended in the main oases of Central Asia. But quantitative research and comprehensive analysis about whether it is suitable or to what degree to extend the drip irrigation technology are lacking. Because it is a so large area and the types of oases are different. In this paper,we picked up the belt as the study area,i. e. Piedmont Plain Oasis in the north and south of Tianshan in Central Asian-Piedmont Plain Oasis in the north and south of Tianshan in Xinjiang-Piedmont Plain Oasis in the north and south of Qilian Mountain in Qinghai and Gansu. On the basis of understanding the local ecological environment,the suitability evaluation and application prospect of drip irrigation in mainly agriculture area in arid region of Central Asia was analyzed by means of drip irrigation suitability analysis according to the drip irrigation equipment theoretic utilization rate. The results showed that the Piedmont Plain Oases in North of Tianshan in Xinjiang and Piedmont Plain Oases in the north of Qilian Mountain in Gansu are suitable for drip irrigation. And Southern Xinjiang,West and South of Gaidam Basin are very suitable to adopt the drip irrigation technology. While it is unnecessary to change the current irrigation methods in winter wheat into drip irrigation,beet and such sorts of crops can adopt the drip irrigation test in Piedmont Plain Oasis in the north of Tianshan in Central Asia. The Southern Tajikistan Valley is suitable for drip irrigation and has a great potential. The oases in the deserts of Central Asia,Xinjiang,Gansu,Qaidam Basin of Qinghai and so on are very suitable for drip irrigation. Under the guidance of " One Belt And One Road",the oasis in the vast desert in the west of Tianshan Mountain in Central Asia will become into the main area to test and promote drip irrigation technology,which has great potential.
