库存本阅览室与外借库的合并管理

我馆在2005年将中文图书库存本阅览室与中文图书外借库合并成中文书库,进行统一管理。本文结合工作实际,分析了书库合并前分开管理的弊端,阐述了二者合并的意义,提出了合并后的具体管理措施。     

水闸管理的微机通信网络

在水闸管理上,以多台Tp801单板微型计算机、输入输出接口电路、SIO串行通信接口电路、Tp801D板、12吋绿色显示器、打印机等组成一种远距离传送数据的微机通信网络,它利用电话线路作为数据传输的通道,在淮阴市盐东控制工程管理处投付使用。运行稳定,性能可靠,于1985年9月通过技术鉴定。     

入世风险与农村现行双层经营制度的变迁

中国加入WTO之后 ,农民不仅要承担其他国家农民所承担的自然风险与市场风险 ,还要承担因现行双层经营制度带来的预期不确定性的风险 ,其根源在于现行的经营制度呈现出极大的“体制锁定”的色彩。要打破这种体制锁定 ,必须两条腿走路 :诱致性创新与强制性创新并举。既精减机构 ,明确政府的责、权、利 ,又扶植与培育农民联合体 ,增强市场创新主体分摊成本的能力与赢利能力 ,从而确保新体制的生命力与竞争力。     

Study on Site-specific Nutrient Management in Cotton Field

The study on the characteristics of spatial variability of soil nutrients and fertilizer recommendations in cotton field under certain conditions of agricultural management was conducted with GIS and systematic approach for soil nutrient constrains. The results showed that of the spatial variability of soil nutrient was greatly related to the management condition of previous crops. Grid sampling and variable rate application technology (VRAT) were the tools that would hopefully increase fertilizer efficiency. The fertilizers were applied where they were needed and at proper rate. Balance fertilization demonstration showed that fertilizer recommendations according to the available nutrient level in soil could decrease fertilizer cost with 657.4 yuan / ha and increase seed cotton yield by 19.8%. A net profit of the balanced fertilization was 5314.9 yuan / ha higher than that of local fertilization practice.     

水土保持是山丘区经济发展的根本出路

水土保持是山丘区经济发展的根本出路肖秧（四川省人民政府，成都６１００００）四川地处长江上游，幅员辽阔，境内高山峻岭，江河纵横，是一个有一亿多人口的农业大省。由于历史原因，森林曾遭严重破坏，加之人口众多，人均耕地数量少，垦殖指数高，水土流失十分严重。遥...     

Deforestation patterns and their effects on forest patches

Five identifiable patterns of deforestation are recognized - internal, indentation, cropping, fragmentation, and removal - and each has a distinct effect on habitat quality of forest patches in the eastern United States. By overlaying land use maps from 1973 and 1981 for three counties in the State of Maryland (Prince Georges, Anne Arundel, and Wicomico), changes in the interior core area and edge length of individual patches were measured. Forest interior declined by 23.8 km² in Anne Arundel, 16.3 km² in Prince Georges, and 8.4 km² in Wicomico. Within Anne Arundel and Prince Georges Counties, deforestation increased edge length by 52.1 km and 31.2 km, respectively, whereas, within Wicomico, it decreased edge length by 8.7 km. Differences among counties resulted from current land use patterns, percentage of forest cover, and the dominant deforestation pattern.     

辽宁西部半干旱地区油松纯林改造的研究

喀左县位于辽宁西部地区，现存大面积油松人工纯林，不仅改善地力和水土保持效益差，而且火险性强、虫害蔓延成灾、生长早期衰退。为改善其林分生态条件，提高林木生长量和综合效益，在中三家镇对25年生油松人工纯林进行改造试验。结果表明，选择山杏、刺槐、沙棘等乔、灌木树种，利用林间空地、林缘隙地、侵蚀沟壑和疏林地造林，在大面积油松纯林连片地区进行窄带状或块状砍伐后造林，5年后效益显著，林分相对湿度提高了2．2％，土壤有机质含量提高5．4％，土壤含水量提高9．8％，减轻土壤容重３％,林分虫害明显下降，油松树高、胸径生长量分别提高22．6％、19．8％。     

松材线虫病入侵陕西的风险分析

松材线虫病自1982年在我国发现后，扩散和危害呈逐年扩大和加重趋势，严重影响了我国生态安全和经济发展。本文通过对松材线虫病定量的风险分析，得出风险值R=2．775，表明松材线虫病对陕西省而言属于特别危险的林业有害生物，应加强监测、检疫和除治管理，防止传入陕西省并造成扩散危害。     

浅谈高校管理中的人本管理

人是大学最核心的的资源和竞争力的源泉,作为高校的管理应该是以人为本的管理,以人为中心的人本管理是高校管理的核心和发展方向,学校实施人本管理的关键是把教师的工作潜能最大程度地转化为实际效能,成为推动学校各方面工作进步的积极力量.
