工业化水平区域差异与中国能源消费

在对30个省区工业化水平进行了聚类分析的基础上，描述了工业化水平的区域差异。通过对中国煤炭、石油两类非可再生能源的消费在区域工业增长中的判别分析，探讨了区域工业化水平对能源消费水平的影响。这种影响以工业能源密度为动因，促成了区域工业化水平与能源消费总量水平的一致性和差异性。研究结果表明：工业能源密度的降低和能源效率的改进有利于工业化水平提高。     

试论可持续发展的地域公平性

以对“人地关系”、“发展内涵”和“人的位置”等的系统认识为理性基础．所提出来的可持续发展观．非常强调公平性。经典的可持续发展概念对“公平性”的理解，主要是强调时间维度上的代际公平。我们从地理学的研究核心“人地关系地域系统协调共生理论。和区域可持续发展实证研究的理论和实践的双重角度．认为公平性不仅是时间维度上的代际公平．而且是空间维度上的地域公平和群际公平。就地域公平而言．我们认为．它不仅包括相关地域的公平性而且包括次级地域的公平性和背景地域的公平性。地域公平性的这样的理论认识。在指导区域可持续发展的实践中将具有重要意义。     

80年代中国宁夏的“吊庄”：农村区域开发和协调人地关系的新模式

宁夏回族自治区南部以人口超载导致的贫困和水土流失严重著称于世。针对区域开发的这些限制性因素,选择以协调人地关系为指导思想的“吊庄”模式,取得了良好的综合效益。本文主要论述了吊庄移民规划的方针、原则、理论依据、效益和成功经验。     

黄土高原半干旱区侧柏林群落土壤呼吸日变化及季节动态变化特征

Desertification is one of the most serious eco-environmental problems around Qinghai Lake. Based on GIS and RS, GIS analysis was used to obtain the information of spatial-temporal change and different pattern of desertification in each county around Qinghai Lake in four phases of 1976, 1987, 1995 and 2006. Using the function of intersect and overlay supported by ARCGIS, with analyzing attributes of vector RS images, we obtained transition data and established transfer matrix of land-use types in recent 30 years, besides, protracted land-use transition maps of all desertification classes. In further, we analyzed transition quantity and direction of desertification in each county, moreover, reconstructed the process of spatial-temporal evolution of desertification. The results are showed below: (1) it′s the transition between desertified land and others but not in the desertified that played the main role in Gangcha and Gonghe County, while the transfer between desertified lands were greater than that with other land-use types in Haiyan County. (2) Extremely severe desertified land mainly distributes in Ketu and Sand Islands that belongs to Haiyan County, and moderate desertified land in riversides of Gangcha County, also, the light desertification expanded too rapidly to become the most desertified land-use type in the surrounding of Qinghai Lake since 1976. (3) By using relative change rate of desertified land, the regional variability rank from top to toe was Gangcha, Haiyan and Gonghe.     

国家竞争优势论对泛珠三角区域合作的启示

国家竞争优势论是我国目前较流行的国际贸易理论学说,它无论在国家层面还是在区域层面,均对制定相应的区域发展战略具有积极的作用。基于对波特关于国家竞争优势论的理解,阐述了它对我国开展泛珠三角区域合作的若干启示。     

区域旅游协同发展及其理论依据与研究意义

区域旅游协同发展是区域旅游合作的高级形式,应以系统理论、比较优势理论、资源赋存理论、梯度推移理论为基本理论依据。它是实现区域旅游规模经济的必要条件,解决地区旅游经济发展不平衡的重要途径,发挥地区旅游资源比较优势的有效手段,满足旅游者求异心理、提高游客满意度的重要方法。区域旅游整体形象建设的重要举措与旅游规划的重要指导思想对区域旅游发展在理论上与实践上都具有重要意义。     

层次分析法在区域湖泊水资源可持续发展评价中的应用

依据可持续发展理论,区域可持续发展系统一般由人口、资源、环境、经浊和社会五个子系统组成。本文从四个方面（人对资源环境的需求;资源环境的需求;经济发展的需求;社会发展的需求）提出区域湖泊水资源可持续发展的５指标体系。并用层次分析法计算各指标的权重,用于评价区域湖泊水资源可持续发展的保证程度,结果表明：区域湖泊水资源可持续发展指标体系的２６个指标中,与人民群众生活息息相关的居民对水物满意程度（Ｐ１３）     

重大危险源区域事故应急非结构化模糊决策应用研究

针对目前我国应对重大危险源突发事故的管理和决策主要依赖于相关领导或专家掌握的知识及经验的现状,将非结构化模糊决策方法(Non-structural Fuzzy Decision Method,NSFDM)和事故后果模拟方法相结合,以区域范围内受重大危险源潜在事故影响的企业为决策对象,以减小事故影响范围,降低事故严重程度为目标,建立起重大危险源区域事故应急决策的多准则决策方法,以期帮助安监职能部门优化配置应急救援资源,提高应急响应绩效,减少国家和人民的经济和财产损失。以广州市某公司丙烷储罐区为实例,在对其进行沸腾液体扩展蒸气爆炸(Boiling Liquid Expanding Va-por Explosion,BLEVE)事故模拟的基础上,运用非结构化模糊决策方法,对该丙烷储罐区BLEVE事故的处理,提供了应急决策支持。     

可持续发展与区域环境规划

可持续发展理论对区域环境规划提出了新的要求。本文介绍了可持续发展与传统发展模式的不同之处，并对如何将可持续发展理念融入到区域环境规划的各个阶段中，提出了相关建议。     

ESTIMATING STREAMFLOW AND ASSOCIATED HYDRAULIC GEOMETRY,THE MID‐ATLANTIC REGION,USA1

ABSTRACT: Methods to estimate streamflow and channel hydraulic geometry were developed for unpaged streams in the Mid‐Atlantic Region. Observed mean annual streamflow and associated hydraulic geometry data from 75 gaging stations in the Appalachian Plateau, the Ridge and Valley, and the Piedmont Physiographic Provinces of the Mid‐Atlantic Region were used to develop a set of power functions that relate streamflow to drainage area and hydraulic geometry to streamflow. For all three physiographic provinces, drainage area explained 95 to 98 percent of the variance in mean annual streamflow. Relationships between mean annual streamflow and water surface width and mean flow depth had coefficients of determination that ranged from R²= 0.55 to R²= 0.91, but the coefficient of determination between mean flow velocity and mean annual streamflow was lower (R²= 0.44 to R²= 0.54). The advantages of using the regional regression models to estimate streamflow over a conceptual model or a water balance model are its ease of application and reduced input data needs. The prediction of the regression equations were tested with data collected as part of the U.S. Environmental Protection Agency (USEPA) Environmental Monitoring and Assessment Program (EMAP). In addition, equations to transfer streamflow from gaged to ungaged streams are presented.
