CHALLENGES AND PROBLEMS：CHINA‘S URBAN GOVERNANCE

Chinaˊs urban reforms have brought social progress and development,but a comprehensive national system of social welfare(for example,unemployment insurance,pensions,medical care and public housing)for new migrants from rural areas is lacking.One of the most remarkable changes in Chinese cities in the last decade was a change in so-cial“equality“,with the rise of new poverty both in individual communities and some social groups in urban society.Howev-er,there is little social assistance and public infrastructure for the migrants.Governments or communities or individual should pay attention to the control of new urban poverty and new slums.This paper consider that it is necessary to launch a successful policy,which include mainly:1)accommodating urban growth through low-cost investment projects;2)ur-ban economy depends heavily on successful macroeconomic policy;3)to broaden the three channels linking adjustment to the incidence of urban poverty;4)to restructure urban economic based on the high or new technology;5)to coordi-nate relationship between urban economic growth and environment management for sustainable development of Beijingˊs metropolitan fringe.     

CHALLENGES AND PROBLEMS: CHINA′ S URBAN GOVERNANCE

China′ s urban reforms have brought social progress and development, but a comprehensive national system of social welfare (for example, unemployment insurance, pensions, medical care and public housing) for new migrants from rural areas is lacking. One of the most remarkable changes in Chinese cities in the last decade was a change in social " equality", with the rise of new poverty both in individual communities and some social groups in urban society. However, there is little social assistance and public infrastructure for the migrants. Governments or communities or individual should pay attention to the control of new urban poverty and new slums. This paper consider that it is necessary to launch a successful policy, which include mainly: 1) accommodating urban growth through low-cost investment projects; 2) urban economy depends heavily on successful macroeconomic policy; 3) to broaden the three channels linking adjustment to the incidence of urban poverty; 4) to restructure urban economic based on the high or new technology; 5) to coordinate relationship between urban economic growth and environment management for sustainable development of Beijing′ s metropolitan fringe.

地理大数据支持下的城市功能区识别研究

准确识别城市功能区有助于精细化城市管理、合理化资源配置。传统的城市功能区识别方法在很大程度上依赖实地调研及统计年鉴数据,不可避免地存在较大的主观性,且受限于数据获取的繁琐性,导致识别过程耗时耗力且效率低下。地理大数据的广泛应用为城市研究提供了一种新的方法和途径,已被用于辅助城市规划建设与管理相关工作。为推广和普及地理大数据在城市功能区识别中的应用,以特大城市为研究对象,基于OSM(OpenStreetMap)路网与互联网位置信息等地理大数据,准确识别了研究区内多种类型的主要功能区,并将识别结果与城市实景予以比较和验证。实验结果表明,基于地理大数据结合区域活跃度指标的空间与时间尺度分析,可以较为准确地识别出符合特大城市规划现状的主要功能区,证明了地理大数据支持下的城市功能区识别的有效性,有助于为城市规划和建设管理等相关工作的高效开展提供参考。

There are three features about the study of the quality of life by means of objective method. First, objective methid is based on the government publication of statistics from which the information of social environment influencing people's life can be obtained by systematic analysis. Second, as a result of social policy and planning development, the quality of life studied by objective method can provide scieatific basis for regulating and making policy. Third, the objective method emphasize that the improvement of the quality of life mainly depends on the effort from the government so as to set up a coordinatly developed environment of community.On the basis of relevant data from the 1991 Yearbook of Urban Statirtics of China published by Statistics Press of China, and using spss, the quality of urban life in China is evaluated.

An approach to theory and methods of urban geomorphology

Urban geomorphology is a new subject, and its theory and practice need approaching and substantiating. This paper deals with the utilization and transformation of landforms in the process urbanization, and the evolvement and unique character of an urban geomorphological environment. Taking an evaluation about catastroability of the urban geomorphological environment in Chongqing as an example, the author introduces a researching method in the urban geomorphology, including selection and quantification of evaluation parameters, a grid method used in mapping and a mathematical synthesizing method to evaluate on a fixed position.
