测井在碳酸盐岩气藏储量计算中的应用

随着测井采集技术和测井资料评价技术的飞速发展,测井技术在储量计算中的应用越来越广泛,所起的作用也越来越重要.四川测井公司经过多年的探索与实践,通过开展探井测井精细解释、RFT地层测试技术应用及测井地震结合储层横向预测技术研究,已形成了一套应用测井资料全面、细致分析地层、构造、储层的测井精细解释技术,1997～2000年间,共完成了36口井的探井精细解释工作,取得了可喜的成果,在碳酸盐岩气藏储量计算中发挥了重要作用.     

Perennial grass management impacts on runoff and sediment export from vegetated channels in pulse flow runoff events

The goal of the United States Congress is to replace 30% of United States petroleum with biofuels by 2030. If this goal will be accomplished, it is estimated that 25-50% of the land enrolled in the Conservation Reserve Program (CRP) have its biomass removed. However, the purpose of many conservation practices enrolled in CRP is to improve or maintain water quality and not to serve as a source of biomass. This study was conducted to determine if biomass removal has an effect on runoff and sediment export from vegetated channels during low intensity storms that occur frequently. In June 2006, 24 channels were created that measured 2 m × 10 m. The treatments of grass species (big bluestem, corn, smooth bromegrass, and switchgrass) and biomass removal (removed, not removed) were applied to the channels in a split-plot arrangement. Three times in 2007 and 3 more times in 2008, a 787 L load of water with suspended sediment was drained on the head and sides of each experimental unit and the entire load of water that ran off was collected, weighed, and sampled for sediment concentration. Biomass removal increased runoff and sediment by an average of 15% over the two years of the study. The channels planted to perennial C4 grasses were most effective at reducing runoff and sediment export, while the corn was consistently the least effective at reducing runoff and sediment export.

美国公司基金会性质初探

美国是基金会最发达的国家，数量多、规模大、活动范围广，在社会经济和政治生活中起着相当大的作用，有第四势力之称。究其本质，美国公司基金会是资本主义制度的产物，旨在维护美国现有制度，在美国社会矛盾中起润滑剂的作用。基金会基金的最终来源仍是工人阶级剩余劳动创造的。客观辨证评价美国公司基金会的作用，既应看到其造福人类，推动美国社会发展的一面，又要看到其逃税，不公平竞争等消极的一面。它既不是“救世主”，也不是“万恶之魔”。     

Analysis of a natural resources management system in the Calakmul Biosphere Reserve

An analysis of the natural resource management system was carried out for the ejido X-kanha located in the northern part of the Calakmul Biosphere Reserve in Campeche, Mexico. Through field research using participatory rural appraisal (PRA), the activities carried out by different user groups were identified. Gender roles as well as age roles were analyzed. Results show that each family depends upon the diversification of productive activities in order to meet economic needs. Diversification of activities is carried out in both space and time, making use of different ecosystems during varied seasons throughout the year. Women's activities correspond to housekeeping and house administration; they take care of home gardens and are responsible for water collection and wood gathering. Men carry out the activities of working in the milpa, cattle raising, honey production, chicle collection, and wood felling.A series of PRA activities carried out with the people of X-Kanha led to the identification of limitations to more optimal uses of natural resources. The characterization of limitations and associated alternatives is used to provide a guideline to aid the efforts of NGOs and other organizations interested in the conservation of natural resources, and for the well-being of the local population.     

趋同与求异──关于城市建筑特色的思考

本文着重谈了三点看法：1．趋同是建筑时代性的表现；2．求异——建筑地区特性的再发现；3．区别对待，大同小异。在第三点看法中提出，住宅与普通的中小型建筑可表现出富有特色的城市背景，另外，创造城市特色，还要更多依赖于整体环境特质的体现反对历史遗存的保护上。     

自然保护地人地关系空间耦合分析方法 研究——以天目山自然保护区为例

人地关系是自然保护地可持续发展的核心命题。从空间协调角度提出自然保护地环境敏感性与人类活动强度的耦合分析方法,探讨人与地二者的空间耦合关系。通过天目山自然保护区的案例研究,揭示了自然保护地人地关系耦合规律,证实了负向耦合是引起生态问题的重要原因,对人类活动针对性的调节可切实缓解人地冲突、改善生态状况。人地关系空间耦合分析方法可相对精准地确定自然保护地的人地冲突空间,明确冲突程度,为自然保护地精细化管理提供科学依据。
