| 2 | Research on the Willingness to Accept Compensation and Compensation Sharing of Returning Land for Farming to Forestry in Zhangjiakou and Chengde Region显示文摘[Objective] The aim was to study the willingness to accept compensation and compensation sharing of returning land for farming to forestry in Zhangjiakou and Chengde region.[Method] Based on the investigation of farmers' willingness to accept ecological compensation in Zhangjiakou and Chengde region,farmers' willingness to accept compensation was quantized,and the calculation model of sharing rate of ecological compensation was established,finally the sharing rate of ecological compensation was calculated choosing water supply quantity as reference.[Result] Farmers' willingness to accept compensation in Zhangjiakou and Chengde region was 2 740.5 yuan/(hm2·a),and returned farmland area was 429 700 hm2 in 2008,so the willingness to accept ecological compensation was up to 1.178 billion yuan/a.In addition,the ecological compensation sharing rate of government was 37.60% in Beijing,42.75% in Tianjing and 19.64% in Tangshan,and their ecological compensation funds were 443,504 and 231 million yuan,respectively.[Conclusion] The study could provide important foundation for the establishment of ecological compensation standard and implementation of ecological compensation in Zhangjiakou and Chengde region. | WANG Yan-xia1,CHEN Xu-dong1,ZHANG Su-juan1,BAI Jie2,ZHANG Yi-wen3 1.Institute of Geographical Science,Hebei Academy of Science,Shijiazhuang 050011,China 2.Computer Department,Hebei Vocational College of Politics and Law,Shijiazhuang 050081,China 3.College of Resources and Environment Science,Hebei Normal University,Hebei Key Laboratory of Environmental Change and Ecological Construction,Shijiazhuang 050016,China | 2011 | Meteorological and Environmental Research2011，2，5： | 3 |

| 4 | EXPERIMENTAL RESEARCH OF EQUILIBRIUM AND NONEQUILIBRIUM DYNAMIC ADSORPTION OF Cd^(++) IN SOIL--EFFECT OF DIFFERENT ACIDITIES AND SATURATION显示文摘This paper studies water and solute transport in soil. It mainly deals with theadsorption behavior of heavy metal Cd++ in soil at different PH values and the dynamic charac-ters of adsorption process in unsaturated state. Through theoretical analysis and experimental re-search, the adsorption isotherm and the equations of dynamic adsorption in saturated and unsatu-rated states are proposed. | Huang Jun-qi Xie Xi-na Bai Yiao-dong, Institute of Porous Flow and Fluid Mechanics, NPCC and Academia Sinica, P.O.BOX 44, Langfang Hebei 102801, P.R.China | 1992 | Journal of Hydrodynamics1992，4，2： | 1 |
| 5 | Effect of Tempered Temperature on Microstructure and Properties of 150mm 610MPa Grade Ultra-Heavy Plates显示文摘The 150mm 610MPa grade ultra-heavy plates was successfully exploited with 320mm casting slab,and the microstructure and mechanical properties was studied under different tempered temperature.The plasticity and toughness are improved obviously in the 1/4 and 1/2 of 150mm ultra-heavy plates by controlling the amount and distributing pattern of ferrite,and the produced plates are successfully used in the construction of hydropower station of Murum in Malaysia. | WU Bin 1,JIN Ru 1,SUI He-long 1,JIANG Zhong-hang 1,WANG Quan-li 1,BAI Xue-jun 2 (1.The Technical Research Institute of Shougang,Beijing 100043,China 2.Qinhuangdao Shouqin Metal Materials Co LTD,Qinhuangdao 066326,Hebei,China) | 2011 | Journal of Iron and Steel Research(International)2011，18，S1： | 0 |
| 6 | Resource Allocation of Agricultural Science and Technology R&D显示文摘The status quo of resource allocation of agricultural science and technology R&D(research and development)both at home and abroad,including the amount and function of agricultural science and technology research funds,human resources in the resources of agricultural science and technology R&D,the efficiency of resource allocation of agricultural science and technology R&D,the management system of agricultural scientific innovation and the operation status of scientific funds,is analyzed.The problems in the current resource allocation of agricultural science and technology R&D are put forward,including unreasonable resource allocation;low efficiency,and low efficiency of the transformation of agricultural scientific achievements.The highly effective resource allocation of agricultural science and technology R&D is analyzed from the aspects of resource allocation structure,environment,channel,spatial layout and industrial chain. | BAI Li,ZHANG Li-ming,LI Xian-song College of Economics and Trade,Agricultural University of Hebei,Baoding 071001,China | 2011 | Asian Agricultural Research2011，3，3： | 0 |
| 7 | 白洋淀上游蓄污工程沿岸地下水污染状况及对居民健康影响的调查显示文摘白洋淀污染一直是国家和河北省所关注的问题。对白洋淀上游蓄污工程沿岸水环境调查表明:饮用深层地下水受到城市工业废水的污染,主要污染物为有机物。污染区儿童贫血率、白细胞计数、舒张压高于非污染区,白细胞吞噬率低于非污染区,居民恶性肿瘤标化死亡比高于非污染区,肝癌标化死亡比明显上升。 | (Investig ative Group on Hygienic Status of Drinking Water in Bai Yang Dian Hebei Province) | 1994 | 环境与健康杂志1994，11，1： | 0 |
| 8 | A STUDY ABOUT SOIL WATER CHARACTERISTIC,CONDUCTIVITY OF WATER AND EQUILIBRIUM ADSORPTION OF CUPRIC ION IN SOIL——A UTILITY EQUIPMENT USED IN SOIL SCIENCE AND ITS ILLUSTRATION OF USE显示文摘A utility equipment used in soil science is designed and installed.The equipment can be used in research pro-grams of soil water and solute transport.Pressure in pressure chamber of the equipment in which a tested soil sam-ple is laid can be adjusted exactly so that we can determine the water content of soil sample.With the equipmentwe can not only study the problems related water movement in soil but also measure some solute,such as cadmi-um,plumbum and so on,adsorption on surface of soil in saturated and unsaturated state.As an illustration of theuse of the equipment,we give the isothermal of cupric ion adsorption in soil.This equipment can be used in the re-search work and application of soil science. | Huang Jun-qi Xie Xi-na Bai Yao-dong Institute of Porous Flow and Fluid Mechanics,Langfang Hebei 102801,P.R.China | 1991 | Journal of Hydrodynamics1991，3，4： | 0 |
| 9 | Analysis of the Genetic Relationships in Chinese Ziziphus with SRAP Markers显示文摘The phylogenic and genetic relationships in germplasm resources of Chinese Ziziphus were studied at molecular levels, for providing new molecular evidences of classification, protection, and utilization of germplasm resources of Ziziphus. The sequence-related amplified polymorphism (SRAP) was assessed to analyse the genetic relationships among 14 species of Ziziphus, 11 cultivars of Z. jujuba Mill., and one outgroup. A total of 580 DNA bands were amplified by 19 selective primers, 570 of which (98.28%) were polymorphic. The average number of polymorphic DNA bands amplified by each primer was 30. The genetic similarities of 26 sample materials were between 0.22 and 0.99. UPGMA method cluster analysis showed that 26 sample materials were classified into six cluster groups with the genetic similarity of 0.28. The results showed that SRAP technique is efficient in studying genetic relationships among Ziziphus, Z. jujuba Mill. and Z. acidojujuba C. Y. Cheng et M. J. Liu which should be treated as one species, and further infraspecific classification of Z. jujuba Mill. should be classified into two subspecies; the scientific names of new taxa, Chinese jujube, and wild jujube were Ziziphus jujuba Mill. subsp. jujuba and Ziziphus jujuba Mill. subsp. spinosa (Bunge) J. Y. Peng, X. Y. Li et L. Li, respectively. Z. xiangchengensis Y. L.Chen et P. K. Chou, Z. montana W.W. Smith and Z. mairei Dode might be originated from same ancestry. Z. xiangchengensis Y. L. Chen et P. K. Chou and Z. montana W.W. Smith should be treated as one species. The infrasubspecific taxon of Z. jujuba Mill. was not suitable to set up varieties. | LI Li, PENG Jian-ying and BAI Rui-xia College of Horticulture, Agricultural University of Hebei, Baoding 071001, P.R.China | 2010 | Agricultural Sciences in China2010，9，9： | 0 |
