生态系统服务测度下市域生态空间管控体系构建

生态空间承载着人类、动植物和自然生态多种过程，是生态系统服务功能的策源地和枢纽区。以实施生态空间管控为导引，借助多源数据和ArcGIS、C-Plan系统工具，核心应用系统保护规划(SCP)技术，建立生态服务测度下市域生态空间管控体系的构建方法。基于此，以哈尔滨为例，以不可替代性为表征实现生态空间测度指标综合与功效评价，构建生态空间关键区识别、功能区优划以及网络格局优化模型，提出“重点保护-分区指引-格局优化”的市域生态空间管控体系，为新型城镇化及绿色发展战略的实施奠定科学基础和提供技术支撑。     

试析森林生态环境价值计量研究中的几种干扰因素

本文就目前影响在林生态环境价值计量研究的几个干扰因素进行剖析。其中主要包括森林生态环境难以进入市场的原因；在林生态环境资源并不是都重要计量；森林生态环境的价值既是哲学的价值也是经济学上的价值；森林的生态环境转移与它的价值转移没有实现统一；森林生态环境价值计量使用的概念需要明确和统一；在林生态环境资源的监测和统计；影子价格理论在森林生态环境价值计量中应用的合理性；森林生态环境资源生产的投入产出进行过程等问题。这些问题如果得到及时解决，将有助于在林生态环境计量的进一步研究。     

The Change of Ecological Footprint and Its Effect on Sustainable Development in Beijing of China

Speeding up the environmental protection and construction is one of the major issues in ＂Greener Olympic Games＂ held in Beijing in 2008. Making a thorough study to find out the reliable measures to ecological resumption in Beijing has an important scientific and practical significance. It can provide scientific basis for making a better decision for ＂Greener Olympic Games＂ held in capital Beijing and development in harmony for society and economy, as well as management for ecological environment. By studying of change of ecological footprint from 1990 to 2003 in Beijing, the paper shows that ecological footprint per capita has a strong relativity with population and GDP, and both of the correlation coefficient between them is about 0.92, as well as the fossil energy land has a position in the lead in ecological footprint items. The study also shows that the ecological capacity per capita in Beijing occupied about 1.25% in global ecological capacity per capita. Began 1990, the ecological deficit in Beijing was about 0.72 hm2, which is at strong unsustainable development at present. Finally, the paper suggests social and economic structure should be adjusted as soon as possible, resources should be strengthen sustainable used and population increasing should be controlled strictly, as well as arable land also should be under control used for built-up areas. Simultaneity, the utilizing ratio of energy sources should be increased, and the consumption of energy sources and ecological deficit in Beijing should be reduced in order to speed up the society and economy development in harmony and sustainment.

Money as Social Exergy

Synopsis It has been proposed that open thermodynamic systems will act to dissipate available energy gradients by self-organizing into coherent structures that, with time, evolve and develop into nested hierarchies – panarchies – that adapt to internal and external changes according to a characteristic adaptive cycle. This paper seeks to apply these ideas in the purely societal realm by investigating the role of money in economic systems. Money represents the value embodied in goods; a value that is separate from the exact nature of those goods. We suggest that money thereby liberates the ‘free value’ of economic desire and that this free value has properties analogous to energy. The result is the self-organization of structures and systems (‘econosystems’) that dissipate this ‘free value’. Econosystems act at different scales, and nested levels of econosystems form a panarchy, having effects that can be observed. In particular, it appears that money facilitates the creation of relationships between econosystem actors, increasing the connectedness of the econosystems that envelop those actors. We have identified a phenomenon whereby freed social value (i.e. money) can aggregate, or pool, at a larger econosystem scale in structures such as banks. These pools act as gradients that actors at the neighborhood scale can exploit for self-organization in the econosystem. Thus, econosystem actors appear to be freed from thermodynamic constraints by using money as a means of self-organization. However, because of these pools of aggregated social exergy, connectedness is increased at the larger scale of the econosystem. The potential consequence of this dynamic is that money may act to push larger scale econosystems toward a state of heightened vulnerability to collapse, while freeing smaller scale actors from apparent constraints. In this way, we propose that money acts to skew information feedback loops between econosystem actors and larger scale structures such as economies and ecosystems.      

由宁夏中部地区的资源开发看生态建设的整体性

宁夏中部地区是宁夏乃至全国的土地资源及能源的重点开发区域。但是，由于其生态环境具有强烈的过渡性、复杂性和脆弱性，以往的资源开发活动已经造成了森林退缩、草场退化、土地沙化、水土流失与土壤盐渍化等一系列生态环境问题。文章指出上述生态问题的产生也是人们在资源开发过程中非整体性行为的作用结果，为此，生态建设要作为一项全社会参与的“系统工程”，从生态经济建设、生态文化建设、生态体制建设与生态工程建设等几个侧面共同入手，只有这样，才能保有以往的生态建设成果，实现本区域生态系统的良性循环。     

浅论滨海红树林湿地的生态功能——以泉州湾为例

红树林湿地主要分布于热带、亚热带淤泥质海岸或河口区潮间带,其在维护海岸生态平衡方面有独特的作用,但是,由于滨海地区城市化、工业化、农业生产等影响,红树林湿地发生明显变化,红树林结构和功能明显退化。本文以泉州湾为例,分析红树林湿地生态功能、影响因子,并提出开发与保护红树林湿地生态功能的若干措施。     

丽水市发展生态旅游的条件评价与措施

浙江省丽水市发展生态旅游具有资源和区位优势条件。本文根据各区域生态旅游资源特点将丽水市分为4个生态旅游区。同时，指出丽水生态旅游发展要以市场为导向，做好科学合理规划；加强生态环境的保护和生态旅游资源的建设；加大区内交通建设力度；重视旅游从业人员素质的培训和环保宣传工作。     

我国农业生态系统营养循环链的断裂与重建

完整的营养循环是农业生态系统健康、可持续发展的重要保障。我国传统农业属于环境友好型生态农业。农业生态系统的营养循环结构完整，持续健康、繁荣。但是，随着工业化、城市化、市场经济的发展以及农业耕作方式的转变，农业生态系统营养循环的结构遭到严重破坏，导致一系列资源、环境、经济与社会问题。通过秸秆还田以及城市生活废弃物（排泄物、厨房垃圾等）向农业生态系统的返还，重建农业生态系统完整的营养循环，是我国农业生态系统持续健康发展的必由之路。
