Managing the Commons Texas Style: Wildlife Management and Ground‐Water Associations on Private Lands1

Abstract: As nearly all of Texas’ rural lands are privately owned, landowner associations for the management of white‐tailed deer and ground‐water have become increasingly popular. Deer are a common‐pool resource with transboundary characteristics, requiring landowner cooperation for effective management. Ground‐water reserves are economically important to landowners, but are governed by the “rule of capture” whereby property rights are not defined. One ground‐water association and four wildlife management associations (WMAs) were surveyed to characterize their member demographics, land use priorities, attitudes, and social capital. Members of the ground‐water cooperative were part of a much larger, more heterogeneous, and more recently formed group than members of WMAs. They also placed greater importance on utilitarian aspects of their properties, as opposed to land stewardship for conservation as practiced by members of WMAs. If ground‐water association members could be more locally organized with more frequent meetings, social capital and information sharing may be enhanced and lead to land stewardship practices for improved hydrologic functions and sustained ground‐water supply. This, coupled with pumping rules assigned by the local ground‐water district, could yield an effective strategy that is ecologically and hydrologicaly sound, and that allows rural provision of water supply to urban consumers.

城镇建设用地需求预测与配置研究

针对我国现行城镇建设用地预测方法存在的问题，对城镇建设用地预测方法进行了探索性研究；通过构建科学的建设用地需求预测方法，为土地利用规划提供科学依据。在C—D生产函数的基础上，提出了土地、资本与产出GDP的要素关系模型、恩格尔系数与人均建设用地面积关系模型和时间序列的ARIMA建设用地模型。对成都市城镇建设用地总量进行了实证分析，对4种预测方法的结果进行了定量评价，并据此提出成都市建设用地的配置方案。     

旅游规划中的目的地竞合分析——以芜湖市为例

经过多年旅游开发实践的驱动，我国旅游规划工作有了长足发展，但目前仍存在旅游规划模式化，忽视规划区的“地方性”，缺乏规划区的区际与区内旅游空间竞争与合作关系研究等，使规划区功能、产品、市场等定位不准，策划的项目与周边区域雷同等问题突出。在旅游规划中加强目的地竞合分析是寻求目的地特色、准确定位、优化线路、创新产品体系等的前提和重要、有效的技术手段。阐述了旅游目的地竞合分析的内容和方法，并以芜湖市为例，对芜湖市的区内和区际旅游空间竞合进行分析，提出了芜湖市旅游功能定位、战略目标与空间布局。     

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。     

元素赋存状态的研究及其在矿产资源综合利用中的意义

元素赋存状态的研究是指研究元素在矿石中的存在状态，且尽可能对其进行定量研究的工作。目前元素赋存状态的研究手段很多，不同的矿山和企业可根据实际情况有选择地采用。我国是资源短缺型国家，元素赋存状态的研究是资源合理有效利用的关键，可以避免盲目开采对资源的浪费和经济上的损失。     

Assessing differences in chemical disaster proneness: The community chemical hazard vulnerability inventory*

The burgeoning number of accidents with dangerous chemicals makes it incumbent upon community and regional planners to systematically deal with this problem. The first step invariably involves the assessment of the likelihood and type of incident which may impact a given area so that disasters may be averted or, at least, their effects mitigated. This paper presents one such assessment scheme, the Community Chemical Hazard Vulnerability Inventory (CCHVI). This instrument, aside from considering the type and volume of substances posing a threat to a designated area, considers the physical and human resources available, as well as the general state of readiness of the area (including such things as the interface of emergency-related organizations). The use of such vulnerability assessment instruments allows local emergency planners to identify particular dangers within their communities and permits regional planners to allocate funds for planning according to relative needs.     

THE ENGINEER'S ROLE IN WATER RESOURCES PLANNING1

Engineers have traditionally led the planning effort in water resources developments. The engineer's leadership role in water resources, as well as in many other planning activities, has been challenged by technical and scientific people as well as by the general public for insensitivity to social, aesthetic, ecological, and political problems created by planning. The paper draws attention to the fact that the engineer cannot continue to expect the role of leadership to fall to him unless he prepares himself properly for that role. However, it is brought out that the engineer, by his education and training, is still the best qualified among all the representatives of the various disciplines associated with water resources planning to lead the planning effort if he prepares himself for the task. The requirements for preparation for leading water resources planning are outlined.     

PROJECT 2000, A PLANNING IMPERATIVE1

Time is running out on this country's planners. Generally speaking, the art of planning has retrogressed since the time of Christ. If we are to survive, this will have to be drastically changed by the year 2000. To achieve this, we need to begin to change our thinking, today. We badly need wider social planning, giving us more alternatives-more thought on where we are going. Reasonableness requires blending of planning and construction-but a sharp line of independence is essential. We must think about all the consequences of a particular act. Through intensive professional development and achievement of professional expertise, many outstanding technicians often move into vital decision making positions within their respective agencies. As planners, they see a part of the action but miss the big picture. Problem solutions become restricted to agency or individual authorities and are not always the best alternative. Thus, the planning field is overflowing with solutions to our every problem but many solutions offer spot control, and while the black spot is removed from the garment the white spot remaining from the solution offers little consolation to the wearer.
