高标准农田建设适宜性评价、效益评价及影响因素解析的研究方法综述 总被引：3，自引：1，他引：2
通过大量文献梳理,采用文献资料法、对比分析法、归纳总结法,重点围绕高标准农田建设背景与现状、建设适宜性评价、效益评价、影响因素解析4部分内容进行研究。对比分析当前研究中评价指标的设置方向以及研究方法在原理、优缺点及适用性等方面的差异性,最后进行整体总结与展望。结果表明,当前高标准农田建设工作已取得显著成效;在项目建设前的适宜性评价研究中,评价指标的设置更侧重于区域耕地的自然禀赋条件;在项目建设后的效益评价研究中,从早期注重经济效益评价逐渐发展为经济、社会、生态效益评价并重;在影响因素解析研究中,当前研究仍较为薄弱,对不同建设区域效益提升水平存在差异的解释仍较少。针对研究方法,未来研究应综合考量不同方法的优缺点及适用性。本研究能为科学推进高标准农田建设提供有益参考。 相似文献

By analyzing the process of enterprise information engineering construction and intra relationship among information system requirement, business process modeling, application system constructing and project management, one of 4 meta model composed of requirement engineering, process engineering, application system engineering and support engineering is proposed for enterprise information engineering. The developments and applications of the business processes and its application systems are integrated into the same development space and application space. Basing on this, a prototype system composed of requirement modeling environment, business process modeling environment, application system modeling environment, and support engineering environment has been designed and built, which is used for supporting enterprise information engineering constructing. It is valued for the enterprise information engineering construction in our country. 相似文献

Recently, the increasing concern about the environmental quality of human settlements makes people realize that the attractive environment given by natural ecology also deficiently needs the feedback and protection of nature in some forms so that the natural ecology can be endlessly cycled on its own. Taking the project of German Enterprise Center in Qingdao Sino-German Ecopark as an example, this paper discussed construction of outdoor environment water circulation system using the landscape building method. 相似文献

Based on the introduction of particularity of the construction project and asymmetric information in its implementation, it shows that the project manager may have opportunism behavior, which affects the construction corporation and project manager. A principal-agent theory is applied to set up two models under different risk attitude and which proved that only if the agent were risk-neutral, the principal would get the maximum profit by leasing the project. The opportunism behavior does appear in the optimal incentive mechanism when the agent is risk-avoiding and it is harmful to the principal's benefit. The fundamental way to eliminate opportunism is enhancing the incentive intensity and enforcing outside monitoring and binding mechanism. 相似文献

北京市社会力量参与新农村建设效果与未来展望 总被引：2，自引：1，他引：1
社会力量是新农村建设的重要主体之一。为了解社会力量参与新农村建设的建设效果,填补有关研究空白,本文以北京为例做了实地调查。结果发现,在新农村建设中,多种社会力量积极参与,取得了良好的经济社会效益,其中政府在参与建设和政策引导方面起到了重要的推动作用。但同时,社会力量在参与新农村建设过程中,建设内容及合作方式还相对简单,建设项目偏重直接的经济投资,对医疗卫生、精神文化和社会公益等项目投入不足,一些建设还存在形象工程、破坏环境等问题。鉴于此,本文认为,在引导社会力量进行新农村建设过程中应该做好政策鼓励、舆论引导和组织保障等工作,并充分发挥农民的主体地位,为新农村建设培育良好的氛围。 相似文献

转CpTI基因对棉花根际土壤中微生物的影响 总被引：3，自引：1，他引：2
2006-2007年,采用4个转CpTI基因棉花材料及其受体,于棉花不同生育期取根际土壤,研究了转CpTI基因对棉花根际细菌、放线菌及真菌数量的影响。结果表明：转CpTI基因及其受体材料根际土壤中细菌、放线菌和真菌的数量均随着棉花的生长发育变化,细菌在棉花的花铃期达到高峰,放线菌和真菌在蕾期至花铃期达到高峰,之后随着棉花的衰老均减少。转CpTI基因对棉花根际土壤中细菌、放线菌和真菌的数量有显著影响,细菌和放线菌的数量均比对应受体材料显著增加,而真菌的数量显著减少;从棉花的不同生育时期看,细菌的数量在苗期和花铃期显著高于受体材料,放线菌在不同时期均显著高于受体材料,尤以苗期和花铃期更明显,而真菌的数量在吐絮期显著低于受体材料。 相似文献
