广西横县土地生态经济分区研究

以位于桂东南丘陵盆地的横县为研究区,对土地生态经济分区的原则和指标体系进行了探讨,采用GIS技术建立了包括自然生态、土地资源和社会经济等信息的土地生态经济系统的空间数据库,选择其中40项指标,运用SPSS软件对研究区的21个农业乡(镇)进行了聚类分析,据此将研究区划分为4类8个土地生态经济分区,分析各土地生态经济分区的主要特点,并提出了土地资源可持续利用和生态建设的合理性建议.     

区域旅游产业生态集群的内在机理与培育策略

旅游产业生态集群是适应旅游产业生态化发展要求的最优空间布局模式,它以特有的空间结构和生态内涵区别于一般产业集群。本文以湖北省神农架自然保护区为例,从集群组织体系的构建和生态持续力的培植两方面提出了旅游产业生态集群的培育策略。     

Towards the real green revolution? Exploring the conceptual dimensions of a new ecological modernisation of agriculture that could ‘feed the world’

The challenge to produce enough food is more urgent than ever. We argue that the dominant food regime has responded to this challenge by a ‘narrow’ ecological modernisation process within agriculture which may decrease environmental effects to a certain extent, but also causes new negative side-effects and exposes some important missing links. In this paper we explore what might be a ‘real’ ecological modernisation process, including social, cultural, spatial and political aspects. The central question concerns: is there evidence in practice that agro-ecological approaches can contribute to the future demand for food production, especially in developing countries? We illustrate this by describing examples from Africa, Brazil and China, showing a rich variety of such approaches in agricultural practices.Our conclusion is that agro-ecological approaches could significantly contribute to ‘feeding the world’, and thereby contribute to a ‘real green revolution’; but that this requires a more radical move towards a new type of regionally embedded agri-food eco-economy. This is one which includes re-thinking market mechanisms and organisations, an altered institutional context, and is interwoven with active farmers and consumers’ participation. It also requires a re-direction of science investments to take account of translating often isolated cases of good practice into mainstream agri-food movements.     

贵州喀斯特地区生态经济系统协调发展评价

运用生态经济系统理论与系统协调度理论与方法,阐明了从生态系统供给能力与经济系统需要之间的关系去分析生态经济系统间协调发展的思想,提出了协调度计算方法,以及用协调度与协调发展类型相结合对区域生态经济系统协调发展程度进行分析评价的方法。研究表明,贵州省喀斯特地区存在经济落后、生态恶化、生态经济协调发展水平和层次较低等问题,为此需要进一步开展生态经济系统改良,提高生态经济发展水平,以实现生态建设- 经济发展- 人民富裕的预期目标。
