| To achieve sustainable development the world faces a common issue, is an oasis of economic, social, environmental and other complex subsystems of large-scale systems, the sustainable development of oasis system demands the coordination of the various sub-systems, sustainable development. Oasis system as a result of a self-organizing, adaptive non-linear properties of complex giant system, a factor leading to the slight change in the whole system vulnerable to the structure and function of the catastrophe. Therefore, sustainable development of oasis system studies, the factor should be taken into account different characteristics of a potential catastrophe. In this paper, systems theory, the theory of sustainable development, self-organization theory and catastrophe theory as a guide, an analysis of the dynamic evolution of the oasis system process to reform and opening up 30 years of socio-economic development as the main source of data information to the south-eastern Tarim Basin oasis Qiemo as a typical sample area of the oasis system Qiemo the state of sustainable development are analyzed and evaluated. On this basis, on the basis of completeness, conciseness, coherence, high sensitivity, reliability, regional, dynamic, operational principles of the design of multi-level index system of sustainable development. Evaluation method and the use of mutation on the sustainable development of oasis in the state of the system evaluated for Oasis systems provide a solution to sustainable development and recommendations. The use of polynomial regression model with a combination of mutation Qiemo Oasis established mutation model of sustainable development for the future development of the oasis system for reference.Through the study shows that:(1) of the theory to explore the actual situation of the study area can be drawn, after 30 years of reform and opening up the development of the oasis system has evolved into a self-organizing, adaptive features, open, non-linear complex giant system for the sustainable development of oasis system research and understand the need to consider not only their self-organization, but also should be noted that from the quantitative to qualitative changes, to leap from the gradual nature of mutation, in order to make the system sustainable development, we must make the system coordination with the balanced development of the subsystems to achieve harmony between man and nature the purpose of building a harmonious unification of man-land relationship. Not only to economic development, should be paid to the coordinated development of resources and the environment.(2) through the establishment of index system and evaluation method mutation series evaluation of the study area in the oasis system Qiemo the state of sustainable development identified during the course of the study, the impact of the oasis system factors of sustainable development economic development, social progress, Population carrying capacity and resources. After 30 years of the development process, the oasis has been the rapid development of economy, per capita income of farmers and herdsmen have been greatly improved, but need to see is increasing as the population is gradually increasing the bearing capacity of the limited resources of the oasis, through the comparison of time series have seen some changes.(3) through the establishment of quantitative research Qiemo oasis state model of sustainable development can be seen Qiemo Oasis mutation phenomenon is not currently stable but a gradual process, this is the need to achieve sustainable development of oasis, at the same time in the oasis the development process of economic development and social progress that affect the sustainable development of oasis system, two main factors. However, in the course of the future development of the oasis system will produce catastrophe, we also analyzed using the model, of course, this is not a refusal to have a catastrophe in the oasis system, according to research to make appropriate treatment.
