西部大开发中的农业结构调整思考

西部地区的农业发展直接影响到我国国民经济是否能够持续快速健康的发展，这是由于我国是农业大国，农业人口大约占全国人口比例的80％，而实现西部地区持续健康发展的关键在于对传统农业产业结构的调整，提高农业增长的结构变动效益，树立大农业观念，延长农业产业链，在联产承包责任制的基础上通过经营权的集中规模种植，达到实现农业结构调整生态化和产业一体化目标。西部地区在大开发战略实施中，如何将自身的发展环境劣势转变为优势，提出了农业结构调整模式的构想。     

永城煤电集团滤波装置改造的技术经济分析

根据对永城煤电集团供电系统中存在的主要谐波情况，翔实分析了其所造成的附加损耗和经济损失。针对永城煤电集团用电负荷造成的谐波现状及现有的固定LC滤波装置的特点，经综合分析最后确定选用TCR型静止动态无功补偿装置与两矿现有的LC滤波装置并联，组成TCR＋FC结构。从技术、经济两方面看，具有重大意义。

Environmental protection in the Apuseni Mountains: The role of Environmental Non-Governmental Organisations (ENGOs)

The Apuseni Mountains constitute one of the most interesting parts of the Carpathians in terms of landscape, biodiversity and culture. Yet dislocations are now severe and there are development threats which also require a significant response. On the one hand there are some severe pollution problems associated with mining areas developed in the communist period which require remedial action and the cases of Roşia Montana and Zlatna are discussed. On the other hand, there are forest and pasture zones – especially the Padiş Plateau – which are coming under heavy pressure from farmers seeking to enhance their incomes following the decline of mining and manufacturing which has left many households without salaries. At the same time, tourist pressure is growing. Actions are already being taken to limit pollution damage and develop sustainable landuse practices. There is a national park project linked with nature reserves comprising picturesque landscapes, a rare flora and fauna and distinct geological and palaeotological formations (including fossil ice). There are major tourist attractions and with proper management they could become part of a development programme of the countryside. However it is essential that all stakeholders adopt sustainable practices and this means that official programmes – including the future national park authority administration's work in environment protection and tourism management – are backed up by Environmental Non-Governmental Organisations (ENGOs). The paper reviews their diverse activities and concludes that they are making a very substantial contribution in ensuring that the potentials of isolated regions can be utilised in a manner consistent with nature conservation.

三峡库区经济发展评价

当前三峡库区经济发展存在主要产业经济效益低，国有产业亏损大，产业规模小，城镇经济中心作用弱等突出问题．库区开发必需是持久战和持续发展相结合，将库区基础设施建设放在重要地位，搞好资金、行业、所有制之间的优化组合，大力发展第三产业；要准备用几十年的艰苦奋斗，才能赶上全国平均水平．     

四川省云阳县粮食低产坡耕地的综合冶理

县内土地面积３６．４９万ｈｍ２，坡耕地面积３．４４万ｈｍ２．坡耕地粮食年产４５００－６５００ｋｇ／ｋｍ２．低产原因是土层瘠薄，缺土水肥．采取的综合治理措施有：建设农田基础设施，实行生物－工程措施，推行分带轮作三熟制等．由此粮食年产达１１０００—１２５００ｋｇ／ｈｍ２．

浙江省常山县上震旦统西峰寺组碳酸盐的δ13C和δ18O测定

 作者对浙江省常山县三里亭北九家坞的上震旦统剖面的碳酸盐系统采集的54个样品,作了碳、氧稳定同位素的分析。其中δ¹³C除4个外几乎全为正值,平均值2.16%,这与前人提到过的文德期以δ¹³C负迁移为特征的结论不符。离散变为9.0。最大负峰值出现在剖面近中部的磷块岩层中,可能与海流状况的剧变有关。δ¹⁸O除最末两个为小的正值外,几乎全为负值。
