Design and Implementation of Stud-farm Daily Management System Based on C/S Structure

In order to achieve the computerization and digitization of the daily system of stud-farm, the immunization system technology, racecourse health monitoring technologies and the stud-farm prevention technologies were combined to built the studfarm daily management system. By using Visual Studio 2008 and Microsoft Office Access 2003, an immunization information system was developed based on Client/Server structure and combined with the key immunization link of horses. The system included studfarm immune management and racecourse health monitoring system. The immune management contained immunization information input, the inquiry of immunization information, immunization statistics, immunization-reminding and system management. The racecourse health monitoring system included stud-farm monitoring, horses monitoring and inquiry and statistics of health monitoring. The software realized the analysis and tips of the daily information in stud-farm. The software could record the appropriate data and carry on the statistics. The stud-farm daily management system greatly improved the efficiency of the expanded program about immunization and horses＇ healthy rearing technique.     

石漠化生态恢复过程中土壤磷含量的比较研究(英文)

[Objective] The research aimed to study change law of phosphorus content of soil in karst rocky desertification region(KRD) during eco-restoration process such as Northwest Guangxi Province.[Method] The soil samples were collected from typical KRD in Pingguo County and Yizhou City.The determining quotas of different soil samples such as soil total phosphorus content and available phosphorus content were detected,in addition the soil total phosphorus content,available phosphorus content, urease activity, catalase activity and organic matter content in different soil samples were analyzed comparatively.[Result] Aspect,vegetation type and recovery time generated obviously influences on phosphorus contents in different soil samples.The concrete influence order was listed as follow: phosphorus content in soil of south slope was higher than that in soil of north slope;phosphorus content in soil where Zenia insignis Chun was planted was higher than that in soil of closed forest and that of soil where Dendrocalamus minor Var. amoen was planted,additionally,phosphorus increased with recovery time. Urease activity could be used as a monitoring index of soil fertility because it is related to the change of phosphorus content.[Conclusion] The soil of karst rocky desertification region in Northwest Guangxi Province could be recovered gradually if excessive human disturbance was stopped.If proper natural method of recovery promoted by human was taken,the recovery would reach a better result.

IPM Strategies and Their Dilemmas Including an Introduction to www. eurowheat.org

Information about disease management in winter wheat （Triticum aestiva） in eight European countries was collated and analysed by scientists and extension workers within the European Network for the Durable Exploitation of Crop Protection Strategies （ENDURE）. This included information about specific disease thresholds, decision support systems, host varieties, disease prevalence and pathogen virulence. Major differences in disease prevalence and economic importance were observed. Septoria tritici blotch （Mycosphaerella graminicola） was recognized as the most yield reducing disease in countries with intensive wheat production, but also rust diseases （Puccinia striiformis and Puccinia triticina）, powdery mildew （Blumeria graminis） and Fusarium head blight （Fusarium spp.） were seen as serious disease problems. Examples of current integrated pest management （IPM） strategies in different countries have been reported. Disease management and fungicide use patterns showed major differences, with an average input equivalent to 2.3 full dose rates （TFI） in the UK and a TFI of 0.6 in Denmark. These differences are most likely due to a combination of different cropping systems, climatic differences, disease prevalence, and socio-economic factors. The web based information platform www.eurowheat.org was used for dissemination of information and results including information on control thresholds, cultural practices which can influence disease attack, fungicide efficacy, fungicide resistance, and pathogen virulence, which are all elements supporting 1PM for disease control in wheat. The platform is open to all users. The target groups of EuroWheat information are researchers, advisors, breeders, and similar partners dealing with disease management in wheat.     

Potentials of New Information and Communication Technologies （ICTs） in Agriculture Sector

There is a widespread belief that information and knowledge are vital for rural and agricultural development. Today, generation of new and various information and knowledge sources need new information and communication channels. New information and communication technologies can decrease poverty by promotion rural people access to education, health, government and financial services; overall, they can improve livelihood. The purpose of this study was to identify potentials of new information and communications technologies （ICTs） in agricultural and rural sector. Documentary research and literature review were used as research method. Findings revealed that the most applications for these ICTs in rural and agricultural sector were： E-trade of inputs and outputs, extension and training activities for rural dwellers, advertisement of rural tourism products, knowledge transfer from urban to rural and vice versa, official procedures and geographic information system （GIS） for management of natural resources.

贵州省石漠化敏感性的动态演变与模拟预测（英文）

石漠化敏感性评价是为了识别容易发生石漠化的区域,以评价石漠化对人类活动的敏感程度。根据石漠化的形成机制,分析石漠化敏感性的区域分异规律,明确石漠化问题可能发生的地区范围与可能程度。在遥感和地理信息系统的支持下,该研究以利用贵州省1∶50000地形图和2000年的TM影像,结合贵州省水文地质图,土壤图,地质地貌图,岩组图,政区图以及其他地理基础信息为数据源,生成了贵州省1962年和2000年石漠化的敏感度数据,确定相应的状态转移矩阵,半应用马尔科夫过程模拟石漠化敏感度的动态演变过程和未来演变趋势。在贵州省各石漠化敏感类型中,只有不敏感类型面积在下降,从1962年占该贵国土面积的61.35%下降为2000年的55.55%,同时各石漠化敏感度类型之间相互转换,面积增加幅度最大的是中度敏感类型。预测表明：在未来几十年中,贵州省不敏感地区面积将呈明显下降趋势,中度敏感类型面积呈明显上升趋势,轻度敏感类型面积变化基本趋于平稳,而高度敏感类型和极敏感类型面积都有小幅度上升,说明贵州省石漠化危险程度在加剧。     

基于RS和GIS的云南省曲靖市石漠化土地动态变化研究撤回

以曲靖市为研究对象，借助RS与GIS手段，分析2000-2020年曲靖市石漠化的演变特征，通过栅格统计和计算，得到2000-2020年曲靖市不同级别的石漠化土地规模和变化情况。结果表明，2000-2020年，曲靖地区不同级别的石漠化出现了周期性的变化，重度的和极度石漠化的变化趋于平稳，石漠化防治取得了明显的成效，但是潜在的、轻度的石漠化依然存在。曲靖市的石漠化空间分布呈现出东南部重、中部和西北部轻的总体特征，分布相对比较集中。另外，潜在石漠化和轻度石漠化极不稳定，容易被迁移到更高级的石漠化地区。石漠化区域的治理是一项长期而复杂的系统工程，这个过程既有自然因素，也有人为因素。因此在恢复和治理环境上，要把生态效益与经济效益有机统一起来，而不能单方面地追求经济效益和生态效益。
