摘要
绿洲城市是干旱区内部人类活动最为集中、人地关系最为敏感的区域,绿洲城市研究具有积极的理论和实践意义。本文在回顾绿洲城市研究历程和不同时期研究重点的基础上,分析总结我国干旱区绿洲城市研究中的代表性论题及其主要结论,对绿洲城市不同空间尺度的组织结构特色、绿洲城市化影响因素和机制、绿洲城市发展扩张的区域环境响应以及在水资源约束下绿洲城市发展等方面的理论和实证研究进行了概括评述。今后绿洲城市研究面临良好机遇,通过研究内容扩展、学科交叉综合、新技术方法应用等途径能够得到进一步的发展和深入。
Oasis cities are the typical region of arid zone, which have the densest human activities and the most sensitive relationship between human and environment. It is positively worth studying oasis cities of China for theoretical and practical reasons. The history of research on oasis cities in China is firstly looked back, which started in 1980s, boomed in the middle of 1990s and are deepening in recent years.The emphasized directions of research are different in three periods. Based on many study productions of oasis cities in China, four main representative focuses can be summarized: (1) Exploration of the spatial features of oasis cities. Relying on the background of arid land, oasis cities embody special characteristics in different space dimensions, which are macroscopic layout, urban system and microscopic landscapes, respectively. (2)Research on mechanism of oasis urbanization. Different factors, including landform, water and land resources, mineral resource, human requirements and economic developing levels, have different effects on the forming and developing of oasis cities. All of these factors are acting on development course of oasis cities all along, with different intensions in different stages. (3) Region response of environmental system to the development of oasis cities. Oasis urbanization has been manifested to give negative influences on the environment of some arid areas but to give positive ones in others. (4) Research on the restriction of water to oasis cities. Water resource is the key aspect of development in oasis cities, but is not an absolute barrier. Many ways to sustainable development of water resource in oasis cities are taken forward. The study of oasis cities is facing favorable opportunities in the near future. Three trends can help deepen the study, which are wider study field, crossing and amalgamation of multi-subjects, and synthesis of new methods and new techniques.
