全面推进现代化建设，是21世纪的三大任务之一。水利作为首位国民经济基础设施，在经济和社会的发展过程中有着不可替代的战略地位。全面加快现代化建设，水利现代化必须先行，并适当超前。 1　全面推进水利现代化建设是我省经济社会和水利事业发展的客观要求 　　江苏滨江临海，地处江淮沂沭泗的下游，河湖众多，地势低洼，全省10多万km2的面积承泄上中游200多万km2的来水，汛期80%的地面处于洪水威胁之下，素有“洪水走廊”之称。江苏又处于南北气候过渡地带，降水时空分布不均，水资源也相对紧缺，淮北地区、沿海垦区、丘陵山区水资源不足的矛盾尤为突出，苏南面临着水质型缺水的问题。特殊的地理位置和气候条件决定了江苏是一个水旱灾害频发的省份。据统计，1949年后的50年中，江苏受灾面积在66.7万hm2以上的水旱灾害共44年，其中洪涝15年、干旱10年、水旱交错19年，正常年景仅6年。因此，水利在江苏经济社会发展中始终处于十分重要的位置。江苏近50年经济与社会发展的历史证明，“经济要发展，水利必先行。”刚刚结束的江苏省委九届十二次全会明确提出：“十五”期间要以富民强省、争取率先基本实现现代化来总揽全局。在这种形势下，加快水利现代化建设进程，既是全省现代化建设的要求，也是水利自身发展的要求。 1.1　全面推进水利现代化是江苏社会和经济发展的必然需求 　　江苏经济较为发达，　1999年GDP达到7 700亿元，　居全国第二位，　占全国总量的9.4%；　人均GDP达10 669元，　已接近中等收入国家下限水平。　《中共江苏省委关于制订江苏省国民经济和社会发展第十个五年计划的建议》提出：　“十五”　是江苏全面建设宽裕的小康社会，　为率先基本实现现代化奠定坚实基础的关键时期，　全省GDP年均增长预期调控目标为9%～10%，　人均GDP年均增长8%～9%。　到2010年，　全省GDP在2000年的基础上增长1.4倍左右，　苏南及其他有条件的地方基本实现现代化。　水利作为国民经济重要的基础设施，　必须保持与经济和社会的同步发展，　并适度超前。　随着全省现代化进程的加快，　必然要求加快水利现代化建设步伐，　进一步提高防洪保安能力、　水资源供给水平和水环境保护能力，　为国民经济和社会发展提供更为可靠的水利保障。 1.2　全面推进水利现代化是江苏水利发展到新阶段的客观要求 　　1949年以来，　在历届省委、省政府的领导下，江苏人民 　　　本文为江苏省水利厅黄莉新厅长2000年12月15日在部分省、市农村水利现代化研讨会上的发言，略有删节。  相似文献   

Susceptibility to onion-induced hemolysis in dogs with hereditary high erythrocyte reduced glutathione and potassium concentrations.     

O Yamoto  Y Maede 《American journal of veterinary research》1992,53(1):134-137

The hemolytic effect of onion consumption in dogs with hereditary high erythrocyte reduced glutathione and potassium concentrations (designated HK dogs) was compared with that in clinically normal dogs. Twelve hours after oral administration of boiled onions (200 g/dog), hemoglobin concentration decreased to 84.4% of the initial value in HK dogs; it decreased only to 90.5% in clinically normal dogs. At 24 hours, methemoglobin concentration was significantly (P less than 0.05) higher in HK dogs than in clinically normal dogs. The concentration of erythrocyte oxidized glutathione increased about fivefold at 10 hours in HK dogs, whereas it did not change during the experimental period in clinically normal dogs. In addition, at 12 hours, the proportion of erythrocytes containing Heinz bodies increased to 24.4% in HK dogs, but increased only to 1.2% in clinically normal dogs. Thus, results indicated that HK dogs were more susceptible to the oxidant action of onions than were clinically normal dogs.  相似文献

Spontaneous regression of bovine cutaneous leukosis     

K Okada  A Yamaguchi  K Ohshima  S Numakunai  H Itoh  Y Seimiya  H Koyama 《Veterinary pathology》1989,26(2):136-143

Biopsies of skin from a 2-year-old heifer with spontaneously regressing dermal leukosis were examined. The heifer was not infected with bovine leukemia virus and was negative for tumor-associated antigens of enzootic bovine lymphosarcoma. By hematological standards for bovine leukemia, the heifer was positive at about 60 days post-occurrence of the disease (POD). At 53 days POD, lymphoblastic neoplastic cells in the dermis reacted with anti-T lymphocyte monoclonal antibody by the avidin biotin peroxidase complex method. The cells had intracytoplasmic clustered dense bodies under electron microscopy. From 53 to 83 days POD, figures of the transepithelial elimination (TE) against neoplastic cells and perivascular infiltration of small lymphocytes were in the dermis. Small lymphocytes reacted with anti-T lymphocyte monoclonal antibody. At necropsy there were no neoplastic lesions; there were flat lymph node-like tissues in the subcutis. Many germinal centers were seen in the lymphatic organs. Blood lymphocytes at 46 days POD were stimulated by phytohemagglutinin-P and concanavalin A. Sera, taken until 75 days POD and at necropsy, showed an inhibitory effect on mitogen-induced blastogenesis of normal bovine lymphocytes. These results suggested the existence of a spontaneous regressive mechanism against neoplastic lesions by TE and tumor immunity.  相似文献   

Differentiation of hog cholera and bovine virus diarrhoea viruses in pigs using monoclonal antibodies     

Y Zhou  V Moennig  C O Coulibaly  J Dahle  B Liess 《Zentralblatt für Veterin?rmedizin. Reihe B. Journal of veterinary medicine. Series B》1989,36(1):76-80

Monoclonal antibodies against hog cholera and bovine viral diarrhoea viruses were assayed on organ tissue sections of experimentally infected animals. The animals had been infected simultaneously with both viruses. The antibodies were tested using an indirect immunofluorescence test and an indirect enzyme immunoassay with a biotin/streptavidin/peroxidase detection system. A polyclonal hyperimmune serum was used as a control in direct immunofluorescence tests. Both techniques based on monoclonal antibodies were more sensitive and more specific than the conventional test, the enzyme immunoassay being more sensitive than the immunofluorescence test. Small amounts of BVD viral antigen were demonstrable with monoclonal antibodies in most organ tissues.  相似文献

黄金水  高美玲 《福建林业科技》1993,20(3):29-33

本文报道51个木麻黄(Casuarina spp.)地理种源对星天牛(Anoplophora chinensis(Forster))抗性调查和分析的结果。调查获得数据应用IBM—PC计算机进行逐步聚类分析,将51个木麻黄地理种源划分为高感、中抗、高抗和绝抗4个类群,并进行方差分析,结果表明4个类群木麻黄对星天牛的抗性达极显著差异,因此在星天牛发生严重地区可以选择既抗虫、又抗风,生长较好的C_(33)、C_(39)、C_(44)等种源造林。  相似文献   

The study on site quality evaluation for dahurian larch (Larix gmelinii Rupr.)     

Hao Wenkang  Lang Kuijian  Zhang Yanli  Li Longchang  Weng Guoqing  Huang Mingquan  Wang Xiangguo 《林业研究》1993,4(2):33-42

Site quality of larch (Larix gmelinii Rupr.) in Da Xingan Mountain in Inner Mongolia was studied systematically with about 1000 temporary plots and computer software. The nature of site class and site index curve was discussed in view of general mathematical model of height growth. The height growth of dominant tree of four divisions of forest stands were studied and site index tables were constructed respectively. In order to unify the comparing standard and convenience for management in this region, site index table was constucted too. Based on discussing the action and accuracy of forest type, a series of site quality evaluation (forest type-site index class-site index) was suggested. This subject of study is supported by the National Natural Scientific Fund (No. 39270549).  相似文献
