Population urbanization and land urbanization are two systems indicating the urbanization quality, their coordination guarantees the sustainable development. This paper, based on references and Yinchuan's situation, establishes indicator system and uses range, entropy, coordination degree and coordinated development model to study their coordination between population urbanization and land urbanization in Yinchuan city, with results showing a rising trend of urbanization in Yinchuan during 2000-2014, and an ascending coordination, turning from lightly disordered in 2000 to excellent coordination in 2013. All years are land lagging with the exception of 2011 and 2013 which are population lagging. This paper, aiming at land lagging or population lagging in Yinchuan, presents suggestions on intensifying economy, land extension and optimization and new urbanization so as to maintain the coordination between population urbanization and land urbanization and to keep Yinchuan's sustainable development.
Economic transformation and sustainable development in resources-based cities have been popular in research since the 20th century. China has lots of resources-based cities, it is vital to explore the path to upgrading economic transformation. This paper, reviews the policy settings, transformation achievement and issues in economic transformation and upgrade in China's resources-based cities, such as lagging alternative industry development, extensive resources processing and deviated execution of policy. This paper analyzes resources allocation, scientific innovation, and administrative adjustment and their mechanism from the bottlenecks of economic growth in resources-based cities, and establishes a theoretical framework of economic transformation upgrade in resources-based cities, and presents paths to upgrading economic transformation for resources-based cities, aiming at offering references for sustainable development of China's resources-based cities.
This paper, based on the factors in evaluating safety management of metallic mine tailings, establishes its evaluation index system by determining three level1 indexes organization, execution and routine management, and 12 level2 ones including technical staff, safety rules, and key monitoring. Their weights are given by experts' scoring and the level3 fuzzy matrix to establish fuzzy comprehensive evaluation model, which is used to classify the safety management level of some mine tailings, and all quantitated indexes are validated. This study offers references for promoting safety management level of metallic mine tailings.
This paper, based on situation of sustainable development level of Shanxi’s resources-based cities, establishes an evaluation system for sustainable development level of resources-cities from economy, society and resources, and uses AHP to evaluate Shanxi‘s 11 cities with results showing a relatively strong sustainable development in Taiyuan, Shuozhou and Changzhi, harmonious among economy, society and resources, and a general sustainable development in Yangquan, Jinzhong, Datong, Linfen, Jincheng and Xinzhou, but weak in Yuncheng and Lvliang which need transformation. This paper presents suggestions in increasing sustainable development level for difference cities.
