现代生态理论及技术在城市生态规划中的应用途径

生态城市建设使城市生态规划逐步成为全球城市研究的热点。本文在对城市生态规划的概念厦研究进展厦主要研究内容进行简要论述的基础上，对目前国际上比较流行的生态安全格局理论、生态足迹理论、生态系统健康理论等现代生态理论，以及遥感和地理信息系统技术等先进技术在城市生态规划研究中的应用途径进行了论述。     

遥感技术在小城镇发展规划中的应用

对卫星遥感技术在小城镇发展规划中的应用进行了分析，包括小城镇空间布局信息分析、小城镇区位分析和小城镇环境污染分析，介绍了遥感技术在小城镇变化监测中的应用。分析表明，遥感技术能为小城镇发展规划提供众多基础数据，具有广阔的应用前景，但不能完全取代地面调查。     

主题旅游活动项目策划研究--以峨眉山"2004年百姓生活游"旅游活动项目策划为例

自1992年以来，我国国家旅游局每年推出一个专项旅游产品作为对外宣传口号。为配合此项活动的开展，各地纷纷组织了相应的主题旅游活动。通过主题旅游活动的开展，能够有效地整合区域旅游资源、提升旅游目的地形象、丰富旅游目的地产品类型、促进旅游基础设施和服务设施建设、弘扬当地传统文化。通过对峨眉山“2004年百姓生活游”主题旅游活动项目策划的研究，对主题旅游活动项目策划的理论与方法进行了初步探讨。     

区域风险评价方法研究

基于定量风险评价的基本原理,提出一种区域风险评价方法。主要针对有多个重大危险源存在的区域,在对单个危险源进行风险评价的基础上,应用叠加原理得到描述该区域整体风险状况的定量评价结果。同时考虑了消防部门和医疗机构在事故应急救援中的积极作用,并将其量化为区域风险的补偿系数。通过实例验证了该方法的可行性,展示了该方法的应用效果。区域风险评价方法不仅能够反映区域风险的分布状况,而且对区域重大危险源的规划和布局具有较好的决策支持作用。

环境可持续发展理论体系框架的构建

环境问题包括生态环境与社会、经济与生态环境关系两方面的问题，本文从社：会、经济、文化以及环境科技发展等不同角度论述了环境可持续发展理论体系框架的构建，认为环境可持续发展必须是在体现公平性、可持续性、协调性的基础上，建立以生态思维为基础的社会环境伦理观、发展环境科学技术、实现经济的有机增长，不断完善环境政策与环境法制体系，     

TRANSIENT RESPONSE FUNCTIONS FOR CONJUNCTIVE WATER MANAGEMENT IN THE SNAKE RIVER PLAIN,IDAHO1

ABSTRACT: Increasing demands on western water are causing a mounting need for the conjunctive management of surface water and ground water resources. Under western water law, the senior water rights holder has priority over the junior water rights holder in times of water shortage. Water managers have been reluctant to conjunctively manage surface water and ground water resources because of the difficulty of quantification of the impacts to surface water resources from ground water stresses. Impacts from ground water use can take years to propagate through an aquifer system. Prediction of the degree of impact to surface water resources over time and the spatial distribution of impacts is very difficult. Response functions mathematically describe the relationship between a unit ground water stress applied at a specific location and stream depletion or aquifer water level change elsewhere in the system. Response functions can be used to help quantify the spatial and temporal impacts to surface water resources caused by ground water pumping. This paper describes the theory of response functions and presents an application of transient response functions in the Snake River Plain, Idaho. Transient response functions can be used to facilitate the conjunctive management of surface and ground water not only in the eastern Snake River Plain basin, but also in similar basins throughout the western United States.

Class: an Essential Aspect of Watershed Planning

A study of a watershed planning process in the Cache River Watershed in southern Illinois revealed that class divisions, based on property ownership, underlay key conflicts over land use and decision-making relevant to resource use. A class analysis of the region indicates that the planning process served to endorse and solidify the locally-dominant theory that landownership confers the right to govern. This obscured the class differences between large full-time farmers and small-holders whose livelihood depends on non-farm labor. These two groups generally opposed one another regarding wetland drainage. Their common identity as “property owner” consolidated the power wielded locally by large farmers. It also provided an instrument – the planning document – for state and federal government agencies to enhance their power and to bring resources to the region. The planning process simultaneously ameliorated conflicts between government agencies and the large farmers, while enhancing the agencies’ capacity to reclaim wetlands. In this contradictory manner, the plan promoted the environmental aims of many small-holders, and simultaneously disempowered them as actors in the region’s political economy.
