中国地理学界人居环境研究回顾与展望   总被引:9,自引:4,他引:5  
马仁锋  张文忠  余建辉  王岱  谌丽 《地理科学》2014,(12):1470-1479
人居环境作为人地关系研究的古老而又全新领域,伴随着中国城市化与工业化进程中的环境问题备受地理、建筑、城市规划等学科关注。利用文献计量方法梳理国内地理学16种期刊刊发的180篇有关人居环境研究论文,发现国内研究:1起步晚、发展缓慢,高层次研究成果少且增长慢,以城市内部实证研究为主、理论研究较少;2研究领域主要集中在人居环境的内涵与外延、城市或乡村人居环境评价指标体系与模型、宏观尺度地理环境的宜居性与中观层面城市人居环境分异及其理想模式构建和微观社区单元综合居住环境评价及规划实践等;3综合集成研究的方法体系探索尚未取得突破,当前常用方法中PSR模型和DPSIR模型主要以机理解析为目标,实体指标与主体问卷调查心理指标及经济学方法旨在确定人居环境评判标准体系,当然GIS空间聚类也成为近年运用热点。  相似文献

In order to investigate the impact of urbanization and industrialization on surface water quality,a pilot study of Panzhihua mining town was carried out.The urbanization of Panzhihua region was dominated by industry development and population growth.The level of urbanization showed that it was 18.44% in 1965,and reached 45.99% in 1983.Then,it reached 53.71% in 2005,so the urbanization process was very rapid in Panzhihua region.In the process of industrialization,the level of industrialization was fluctuated...  相似文献

This article tests the explanatory power and interactions among five alternative explanations of environmental knowledge: (1) local information availability, (2) neighborhood characteristics, (3) environmental attitudes, (4) personal empowerment, and (5) information seeking. Using random forest and conditional inference trees, the article analyzes survey responses and finds that attitudes about personal empowerment and frequent information seeking are the strongest predictors of knowledge. The study offers random forest and conditional inference trees as statistical tools for complex data sets and studies that test hypotheses generated from multiple theories. We discuss the influence of knowledge differences over inclusive sustainability discussions.  相似文献

China's industrial output is large and has grown rapidly since 1950. The communist government which took power in 1949 sought to decentralize industry to the interior. Analysis of gross provincial industrial output data based on information statistics indicated a period of increasing industrial concentration from 1952–1957. Thereafter gross industrial output decentralized. Specific industries, however, displayed different spatial patterns. Steel, for example, has become more concentrated, whereas chemical fertilizers and cement showed remarkably dispersed patterns. The patterns reflect a dual structure of industrial production comprised of large, modern, efficient plants and small, less efficient plants producing for local consumption.  相似文献

根据880家国家级农业产业化重点龙头企业地理位置、主营业务等资料,利用相关分析、生态分布格局理论等方法,分析了龙头企业在宏观、微观地域及分行业空间布局特征。结果表明:①龙头企业以东部地区聚集为主,西部地区比重有一定提高,东部地区比重有波动;农业发展规模、经济发展水平较高省份聚集企业多,一省农产品丰富度与其龙头企业数相关性亦很显著;②龙头企业在各省内分布聚集程度不一,总体都以聚集为主,尤其以省会城市或中心城市聚集居多。但河北、浙江省内呈均匀分布;③在县级区域,存在一些龙头企业聚集县、专业化县,东部地区聚集县多,中部地区专业化程度高,西部地区特色产业聚集;④划定的17类龙头企业行业,聚集程度大体可分为四类,但总体上对原料依赖行业聚集程度高,对市场依赖行业聚集程度低。  相似文献

美国工业化阶段的历史评估   总被引:1,自引:0,他引:1  
工业化是通向现代化社会的基本途径。美国是人类历史上最大的工业化国家,曾拥有最为完整的工业体系和最为规范的工业化路径,其工业化经验对同为大国的中国具有一定的借鉴意义。本文依据发展经济学结构学派的工业化阶段理论,主要采用部门结构和人均收入的动态指标,对美国工业化过程的起讫时间进行了界定,然后将该过程划分为轻工业化、重工业化和技术集约化三个基本阶段,并根据产业重心不同将重工业化阶段分解为前后两个半段,并给出了每一阶段的具体时间范围。这种研究有助于从整体上把握美国工业化的全貌,并展现出美国经济崛起的历史轨迹。  相似文献

城市边缘区的土地资源紧缺而利用方式多样,土地利用变化既与城市发展有关又和粮食安全密切联系,因此加强城市边缘区的土地利用研究既必要又迫切。利用1990年和2000年TM影像获取的土地利用数据、 1991~2002年社会经济统计数据,借助GIS空间分析方法以及数理统计方法,系统探讨了北京市顺义区耕地流失的时空格局特征及其驱动机制。结果显示,1990~2000年顺义区流失耕地的57%转为建设用地,43 %转为生态用地。农用地中粮食作物的种植面积大幅减少,菜地和果园面积快速增加。工业发展是耕地流失的第一驱动力;人口城市化、房地产发展等加速耕地流失。  相似文献
