大城市的城市化发展战略和途径研究--以南京市为例

城市化从本质上是一种经济社会结构变动过程，南京市作为长江三角洲的副中心城市和江苏省省会，需要认真研究在经济全球化背景下，如何加快推进城市化进程，发挥中心城市功能，促进城市现代化和可持续发展。城市化水平的提高、大城市中心功能的加强、较为明显的城乡二元结构是南京市城市化过程中的基本特征。南京城市化的发展遇到了前所未有的机遇，江苏省已经提出了大力规划建设以南京市为中心的都市圈，并在2001、2002连续2年扩张南京市区的范围，大大加强了南京市的综合实力。南京的城市化发展主要途径在于提升城市功能，奠定城市化的经济基础；以城市空间优化为支点，以基础设施建设为引导，提高城市现代化水平；增强中心城市辐射功能．带动城乡一体的发展。推进南京城市化的进程还必须要制定一些政策和措施傲保证，如加快户籍制度和土地制度的改革、加大投资融资的力度、制定各类切实可行的规划等等。     

生态社区综合评价指标体系的初步探讨

生态社区的出现和发展一直广受关注，建立生态社区综合评价指标体系对于生态社区的实践和发展具有重要的意义。本文通过对社区可持续发展理论，生态平衡理论以及生态社区本身系统特点的探讨，尝试建立一个综合评价指标体系，同时对评价指标体系应体现的功能，以及评价指标体系构建的原则做了初步探讨。     

Study on Assessing Economic Vulnerability of Small Island Regions

The main purpose of this study is to assess economic vulnerability of small island development regions as part of their sustainability constraints. By combining economic and environmental time series data, we assessed a composite index of economic vulnerability which is constructed from three exogenous variables, namely economic exposure, economic remoteness, and economic impact of environmental and natural disasters. We used the Amami Islands, Kagoshima Prefecture, Japan as the case studies for this paper.The results indicated that using a gross island products based valuation index, Kikaijima is the most vulnerable island in the Amami Islands with a composite economic vulnerability index (CEVI) value of 0.678, while by using a per capita based index, Okinoerabujima is considered the most vulnerable island with a CEVI value of 0.680. From the results we also revealed that smaller islands have relative higher vulnerability than the bigger one, which also confirms some previous country-level vulnerability studies.However, it is matter of fact that some islands that have relatively high vulnerability also have good economic performance as shown by their per capita income. In this regard, it can be argued that the success of these small islands could have been achieved in spite of and not because of their inherent vulnerability conditions as an indicator of sustainability constraint. Regarding these findings, we also examined a comparison between vulnerability results and the preliminary concept of an island's resilience in order to capture another perspective on sustainability assessment in a small island region.     

大型水利水电工程实施占用耕地补偿制度的思考

本文在分析长江三峡工程用地特点的基础上。对大型水利水电工程实施耕地补偿制度中的问题和困难进行调查研究，认为应从新的视角来认识大型水利水电工程的耕地占补平衡问题。进而探索耕地补偿制度实施的新途径和新方式。应在耕地总量动态平衡政策适当调整的基础上．将“以地补地”和“缴费补地”的方式相结合。既通过土地整理．在提商土地质量的前提下增加耕地的有效面积：又要落实耕地开垦费．扶持库区的土地整理。从而使库区的耕地占补制度顺利实施。     

Study on the Balance of Agricultural Water and Land Resources on Ningxia Plain

The article puts forward the process and means of regional water and land balance research, and then from two scenarios which are the balances under natural regulation and human intervention, calculated and analysed the balance between water and land on Ningxia Plain. For the balance under natural regulation named farmland water balance, using farmland water resource balance equation, the research estimated the monthly farmland＂ water balance of 8 major crops for all of the 12 counties on Ningxia Plain in the period of 1960-2001; for the balance under human intervention, the research estimated land-use water balance equation of the counties in 2000, and calculated the balance between land use and water resources including irrigating water of all the 12 counties on Ningxia Plain. Results showed that ①precipitation can not meet the water demand of the crops for growth and development on Ningxia Plain, and water shortage is the primary character of farmland water balance under natural regulation. ②the diversity of water and land balance of different counties is distinctly influenced by the crop structure, water quantity for irrigation and irrigation level. ③Irrigation water could meet the crop water demand on Ningxia Plain in 2000, but there was not much space to expand irrigating cultivated land.

Barriers Beyond the Partners: Bureaucratic and Political Constraints to Implementing Joint Forest Management in Tamil Nadu,India

Whereas past research has treated co-management of common pool resources as if villagers and project implementing authorities were the only relevant actors, numerous external factors beyond the control of these two partners create barriers to successful co-management. This paper draws on discussions with Forest Department officials to examine the influence of these forces on the outcomes of Joint Forest Management (JFM) in Tamil Nadu, India. An empirical inquiry into the operational aspects of JFM indicates the important roles of political parties, powerful people, and other state institutions and functionaries as well as the flow of foreign funding. Further, the strong demand by local people for socio-economic development interventions as opposed to improvement of degraded forests belittles the role of the Forest Department relative to other departments. Numerous other conditioning factors and relationships are explored. The authors call for reforms in public governance to allow better participation of all the actors involved for this participatory management approach to succeed and sustain.     

论环境产业

本文在可持续发展视角下,把环境的保护、修复、维护的生产活动及与之直接相关的服务活动称为环境产韭,包括发挥减少、避免污染环境作用的资源再利用鼗和发挥治理污染物与修复、改善环境作用的环境维护业.通过探讨环境产业的内涵、发展历程、运行机制和在产业体系中的位置与作用,指出环境产业是在法规保障下政府强行推动产生和发展起来的,是产业体系中不可缺少的重要组成部分;考虑自然环境对社会行为的影响,改进政府行为构建适台环境产业与传统产业协调发展的经济体制是加快发展环境产业的关键.
