The limitations and needs for optimal use of these technologies are discussed, such as the limited advanced technical knowledge and skills, low awareness and capacity, unclear link between GIS output and policy making, lack of supporting policies and standards, lack of a wetlands geo-information networklimite, and the use of these techniques in wetland research. It is suggested that for realising true applications of RS, GIS and GPS technologies, the availability, accessibility, reliability, homogeneity, and continuity of wetlands-related geo-information enabling environment, policies and standards, and funding are needed.展开更多

The study showed that:in accordance with the benefits and harms of residential environment to residents,the livability of urban residence in Shihezi City could be graded into seven degrees;the most suitable site could be found in the area between Beiyi Road and Beiwu Road to the east of Xihuan Road,which was close to school,supermarket and park,and was the most ideal residential area in Shihezi City.展开更多
