Abstract:

本文在分析了生产建设项目防治措施布设原则的基础上,分析了影响防治目标达到因子,并对防治目标、防治指标、效益分析与措施配置关系进行了研究,提出防治目标是水土保持方案措施配置后必须达到的最低要求,效益分析是根据水土保持方案措施配置能够达到的防治指标,措施配置是达到防治目标的方法。

高素华,玲玲
气象 , 2005, DOI: 10.7519/j.issn.1000-0526.2005.06.017
Abstract: 采用最大可能蒸散、作物实际蒸散、水分盈亏、水分订正系数评价了黄土高原多沙粗沙区主要作物(春小麦、冬小麦、春玉米、夏玉米和棉花)和草地生长季水分供需状况,结果表明,需水量:冬小麦>棉花>春玉米>春小麦>夏玉米:水分订正系数:春玉米>夏玉米>棉花>春小麦>冬小麦。草地需水量为350~450mm,水分订正系数0。95以上,水分供需矛盾小,实施退耕还牧无论对缓解水资源短缺,还是改善生态环境,在黄土高原多沙粗沙区都是十分有效的措施。

黄土高原多沙粗沙区生态环境评价
高素华,刘玲,玲玲
气象 , 2005, DOI: 10.7519/j.issn.1000-0526.2005.06.018
Abstract: 以水土保持作用系数、降蒸差、初级生产力为评价因子,对黄土高原多沙粗沙区的生态环境现状进行了评价,并根据近40年气候变化的规律及国家气候中心gcm模型对未来50年气温、降水的预测结果,对未来该区生态状况进行了预评估。提出,要改变生态环境脆弱、生产水平低下、资源利用和潜力发挥受阻的局面,进行生态环境建设,实行农业结构调整,宜林则林、宜草则草、宜沙则沙,是十分有效的途径。

Abstract:
水土保持是发展新型现代农业的重要基础。对改善环境、保护自然资源,提高资源使用效率发挥着重要作用。本文在分析水土保持对农业发展起到的重要作用基础上,从水土保持为新型现代农业创造有利条件,缓解水资源供需矛盾、改良土壤、为新型现代农业奠定基础,减少自然灾害有利于新型现代农业发展与生态环境改善,为农村可持续发展提供支撑、为实现山丘区新型现代农业可持续发展提供保障等方面探讨了水土保持与发展新型现代农业之间的关系,最后还就做好新型现代农业水土保持工作提出了几点建议。
Soil and water conservation is the important foundation of developing new types of modern agri-culture. It plays a big role in improving the environment, protecting the natural resources and in-creasing the efficiency of resource use. Basing on the analysis of the important role that soil and water conservation plays in agricultural development, this article discussed about the relationship between soil and water conservation and the new types of modern agricultural development, from soil and water conservation to create favorable conditions for the new types of modern agriculture, to alleviate the contradiction between supply and demand of water resources, soil improvement, and laying the foundation for the new types of modern agriculture, to reduce natural disasters favoring the development of the new types of modern agriculture and ecological environment improvement, to provide support for rural sustainable development and to provide the guarantee for the realization of the new types of modern agricultural sustainable development of the hills district. At last, some suggestions also were put forward to make new modern agricultural soil and water conservation work well.

Abstract:
水是生命之源,土是生存之本,水土资源是人类生存和发展的基本条件,是不可替代的基础资源。纵观世界主要国家和地区水土资源治理及其立法和实践,大都将流域综合治理作为其核心内容之一,并侧重于从流域整体层面维护河流健康、公平公道利用水土资源。由于流域水土资源开发、利用和保护与当地的社会、经济、文化等因素关系密切,因此各国和地区流域综合治理的制度表现形式亦有所不同。美国和日本在流域综合治理方面都是起步比较早的国家,有着丰富的经验,他们的一些先进技术,法律制度,管理体制等值得很多国家学习。本文通过对美国、日本水土保持相关法律制度与管理体制的综合评述,结合美国甜水河小流域综合治理和日本山洪灾害及水土流失治理的砂防工程的成功经验,分析了两国在流域水土保持综合治理的法律制度与管理体制方面的优势,为我国流域水土保持综合治理提供借鉴与参考。
Water is the source of life; soil is the root of survival, water and soil resources as the basic conditions for human survival and development are not be replaced. Throughout the world’s major countries and regions soil and water resources management and legislation and practice, most of them regard the watershed management as one of its core content, and focus on maintaining the health of the river from the overall level, fair and reasonable utilization of water and soil resources. Since the basin soil and water resources development, utilization and protection are closely related with the local social, economic, cultural and other factors, the form of integrated watershed management system in different countries and regions is not the same. The United States and Japan in terms of watershed management started relatively early and have a rich experience in integrated watershed management; some of their advanced technology, legal system, management system are worth learning for many countries. In this paper, based on the comprehensive review on Soil and Water Conservation legal system and management system of United States and Japan, combined with successful experiences of American Sweetwater River comprehensive management and Japanese Soil Conservation for mountain torrents and soil erosion governance, we analyzed the advantages in legal and management system of comprehensive harness of watershed soil and water conservation of the two countries to provide a reference for our country of the comprehensive management of watershed.

科学通报 , 2007,
Abstract: 用密度泛函B3LYP/6—311G^*和高级电子相关耦合簇CCSD(T)/6—311G^*]方法计算研究了CBr2与CH2O的插入反应机理,全参数优化了反应势能面各驻点的几何构型,用内禀反应坐标(IRC)和频率分析方法,对过渡态进行了验证.研究结果表明:反应(1)是单重态二溴卡宾与甲醛插入反应的主反应通道.该反应由两步组成:(i)两反应物首先经一无能垒的放热反应,放出8.62kJ·mol^-1的热量,生成中间体IM1;(ii)IM1经过渡态TS1,发生H的转移,生成产物P1,其能垒为44.53kJ·mol^-1.用经Wigner校正的Eyring过渡态理论研究了不同温度下该反应的热力学和动力学性质.从热力学和动力学的角度综合分析,在1atm(101325Pa)下,该反应在温度为200~1900K时进行既有较大的自发趋势和平衡常数,又具有较快的反应速率.
