县级土壤环境功能区划研究与示范——以登封市为例   总被引:1,自引:0,他引:1  
土壤是人类赖以生存与发展的物质基础,土壤环境功能区划是合理开发利用与有效保护管理的重要基础性工作。土壤环境功能区划工作亟须详细展开,且区划方案因尺度不同而异。县级土壤环境功能区划结果要求更具体、可操作性更强。文章深入分析了县级土壤环境功能区划的区划思路、区划原则、区划方法、区划依据与指标体系等区划方案,并以河南省登封市为例进行县级土壤环境功能区划示范研究。登封市土壤环境功能区划分为4级:一级区划分为生产功能区、生活功能区、生态功能区等3类;二级区划分为基本农田种植区、一般农业发展区、商品林生产种植区、农村居民区、城镇建设区、独立工矿区、港口与交通用地区、生态公益林种植区、生态安全控制区、自然景观与文化遗产保护区、湿地保护区、草地保护区等12类;三、四级区划分别根据土壤环境质量现状、潜在风险等进行空间100m格网大小评价并各划分为5个等级。该研究关于县级土壤环境功能区划方案与示范应用,为土壤环境保护与可持续利用提供科学参考,也可为其他地区县级土壤环境功能区划提供科学借鉴。  相似文献

根据系统论观点,协调是复合系统中各子系统在发展演化过程中的和谐共生关系。城镇化与农业现代化的协调度是指二者在发展过程中的和谐一致程度。文章采用空间描述方法构建系统协调状态测度模型,并以重庆2000~2012年数据为样本,对其功能分异明显的五大功能区城镇化与农业现代化发展的协调度进行实证分析。结果表明,重庆城镇化与农业现代化的协调度在2000~2006年较为理想,但从2007年起,城镇化发展指数的增幅明显高于农业现代化发展指数的增幅,协调度几乎处于濒临失调的状态。其中,五大功能区协调度的变化趋势特点各异。就2012年而言,都市功能核心区、都市功能拓展区、城市发展新区、渝东北生态涵养发展区和渝东南生态保护发展区协调等级分别为5级、5级、8级、2级、2级,分别处于濒临失调、濒临失调、中级协调、高度失调、高度失调状态。该文认为,要积极建构城镇化和农业现代化协调发展的制度基础,将城镇化作为实现农业现代化重要动力,依据区域资源禀赋和产业基础推进区域特色城镇化发展。  相似文献

都市农业功能在不同程度的都市生态敏感区内所发挥的经济与生态效益各不相同。基于重庆市沙坪坝区遥感影像数据与自然资源、社会经济数据,从自然环境背景、人类活动干扰等2个方面构建了重庆市沙坪坝区生态敏感性评价指标体系并对该区进行了生态敏感性评价与区划。在对各生态敏感区的生态环境特征与生态敏感性进行分析的基础上,对沙坪坝区进行了都市农业功能区划。结果表明:沙坪坝区可以划分为高生态敏感区、中生态敏感区、低生态敏感区及不敏感区;基于生态敏感性分区结果,全区划分为3个都市农业功能区(都市农业生态涵养发展区、都市农业主体功能区及都市农业多元扩展区)与7个都市农业功能亚区(生态屏障亚区、生态补偿亚区、果蔬产业亚区、花卉产业亚区、创汇农业亚区、科普教育亚区及休闲体验亚区);针对各功能区与亚区提出了相应的都市农业功能调控方案与分区发展策略。  相似文献

The primary objective of this paper is to examine changes in the level of output, prices and exports of major export crops resulting from the Structural Adjustment Program (SAP) in Nigeria. THere two main sources of data: the Central Bank of Nigeria (CBN) through its annual reports, Economic and Financial Review, and the Nigerian Federal Office of Statistics (FOS) through its Trade Summaries. Although the SAP led to appreciable increases in output and producer prices, its effects on exports were insignificant. The implications of these for the implementation of the program are explored.  相似文献

This paper aims to analyse and draw together results from similar studies in England, Switzerland and France which investigated farmers’ understanding of soil and compared it with that of scientists, researchers and advisors (collectively called scientists in this analysis). A range of methods were used across the three studies and different theoretical approaches, looking at forms of knowledge, local practice of knowledge production and conceptions of reality, were employed to explain the results. Despite the different contexts, methodologies and theoretical approaches in the three studies, the results reveal similar patterns of difference in farmer and scientist understanding of soil. In the English study, farmers demonstrate a ‘know-how’ form or intuitive working knowledge of soil while advisors rely on scientifically established forms of ‘know-why’ and seek to understand and explain soil processes. Similarly in the Swiss study farmers’ and scientists’ differing perceptions are directed and shaped by their respective aims, methods and context of work. In the French study, farmers and researchers are shown to have different conceptions of soil, they attribute different meaning to the same activities, and use different words and language to describe the same features. In all three studies understanding is shown to be cultural and contextual, as such an integrative theoretical framework is proposed.  相似文献

森林生物多样性评价模型的改进   总被引:3,自引:0,他引:3  
针对2002年的评价模型中的不足,提出了新的改进后的森林生物多样性变化的评价模型,并在我国第六次森林资源清查(1999~2003)资料的基础上,对1973~2003年我国森林生物多样性的变化进行了补充评价。评价结果表明:我国森林生物多样性的压力越来越大,压力指数由1973年的100,上升到2003年的199.10,上升了1.99倍;森林物种多样性总体的下降趋势已有一定幅度的改变,森林物种多样性指数增加了31.12%。森林生态系统多样性和森林生物多样性先逐渐上升,尔后又下降,第六次森林资源清查时又有所恢复,并分别上升了4.67个百分点和17.90个百分点。  相似文献

Abstract

In this paper, two approaches which are characteristic for Research & Development and Marketing departments are compared. First, R&D versus Marketing orientations are explained, then the major differences between them are presented. The integration of both approaches may improve competitive advantage of the food industry. Factors stimulating such integration are presented on the basis of data from real business circumstances. Innovation is regarded as a major source of competitive advantage of company. Therefore, integration in sensory methodology, that is commonly but differently used by R & D and Marketing departments, may contribute to the improvement of innovation practices and successful business performance. Finally, the role of consumer tests, oriented for marketing and product development, is illustrated.  相似文献

Although trust research has been extensive and substantial, the constitution and actual merits of trust in land use planning remain nebulous. What do participants of a local land use planning process actually mean when they say they trust the planning committee? How important is participants’ trust in the planning committee in shaping their perceptions of the planning process and their cooperation in it? To explore the everyday meaning of trust in the specific context of local land use planning, semi-structured interviews with the participants of a local planning project in Switzerland were conducted (n = 9). Based on these results, the constitution and the relevance of trust in the responsible planning committee among a wider circle of participants were assessed (n = 66). The results show that participants trust the planning committee if they perceive its members as competent, honest, open, fair, reliable, reciprocating, respectful and committed. Interestingly, a considerable part of trust in the planning committee hinges explicitly on whether the committee incorporates the personal interests of the participant. Trust is indeed vital to participants’ belief that a meaningful discussion and cooperation with the members of the planning committee is possible. However, trust is neither a guarantee for people's approval of planning decisions nor for their cooperation. One implication of the findings is that in order to evaluate trust-building practice comprehensively, it is necessary to first understand the specific everyday meaning of trust for ‘real people’ in real planning processes.  相似文献

Since the late 1980s, markets involving agricultural land have emerged in the Socialist Republic of Vietnam. One major reason is that collective farms, previously a central feature of the country's political economy, ended. And a major reason for that was villagers' everyday politics gnawed the underpinnings of the collectives until they collapsed. Rural households, for the most part, wanted to farm separately. Today they do. Land is not privatized, however. Farming households have land use rights, not ownership. This tempers markets, as do other conditions arising from contending schools of thought in Vietnam about how land should be used, distributed and regulated.  相似文献

This project was initiated to promote conservation agriculture (CA) in Tanzania so as to improve the food security and rural livelihood of small- and medium-scale farmers through the scaling-up of CA as a sustainable land management (SLM) tool as well as increasing the numbers of SLM-CA farmer field schools (FFS) in communities. The project had two phases from 2004 to 2010. It was funded by a Government of Germany trust fund and implemented by the Food and Agriculture Organization of the United Nations (FAO) and the Ministry of Agriculture in Tanzania. The project pilot districts include Arumeru (Arusha and Meru Councils), Karatu, Babati, Hanang and Moshi districts. CA has been shown to offer positive elements that could contribute to fighting hunger and poverty.  相似文献

The paper proposes a materialist–utopian perspective for explaining the persistence of community in the Andes by drawing upon Lacanian theory and the thought of the Peruvian Marxist José Carlos Mariátegui. What characterizes the Andean comunidad are not notions of belonging and identity, but the existence of a fundamental antagonism (what I call the ‘Real of community’). The argument unfolds ethnographically. Usibamba, a peasant comunidad in the central Peruvian Andes, is known as a highly egalitarian and disciplined comunidad. However, a disjunction exists between deep‐seated aspirations of justice and egalitarianism and the particularistic interests of families and individuals. This disjunction manifests itself in a contradictory, schizophrenic regime of discipline and negotiation that produces ‘split subjects’. Desiring development and the staging of theatrical performances of egalitarianism enables Usibambinos to deal with this disjunction and to present an image of unity and determination. I conclude that the comunidad persists through ‘impossible political acts’ brought about by a residual but growing category of landless comuneros who constitute ‘the part of no part’, the uncounted or unnamed.  相似文献
