论工业反哺农业与城乡一体化发展

农业现代化研究 , 2006,
Abstract: 工业反哺农业是实现城乡一体化发展,寻求社会公平发展的有效途径。城乡经济的交流和渗透是双向的,弱化城市与农村中的任何一方面不仅不能实现城乡的协调发展。财政转移支付是工业反哺农业的主通道,通过构建农村公共服务体系,形成以财政投入为导向,财政投入、外资投入、民资投入、金融信贷投入相结合的多元化投入机制。新时期乡镇企业反哺农业赋予新内涵,依靠乡镇企业发展,实现劳动力转移促农,农产品加工和产业化经营促农,建农补农实现反哺促农,小城镇建设与乡镇企业发展相互促进实现以城带乡促农。

Abstract:
公路建设的生态环境影响是多方面的,项目永久占地会造成土地上原有植物的消失,常见的人工植被可在砍伐后采取异地恢复等措施来进行生态补偿,但名木古树等具有特殊的价值和意义,需进行特殊保护。本文分析了公路建设对古树的影响,对常见的保护措施进行了总结,以衡山县城连接线项目为例,选取了最为合适的方式对项目涉及的古树进行了有效保护,对同类项目具有参考价值。
Highway construction affects the ecological environment in various ways. Permanent occupation of land causes the disappearance of the original plant; some common artificial vegetation can be recovered in other places after they are felled, which compensates the ecological damage. However, the ancient and rare trees have specific value and significance, so they need special protection. This paper analyzes the influence of highway construction on ancient and rare trees, and summarizes some frequent protective measures. Moreover, it takes Hengshan-Nanyue highway connecting line project as an example, and selects the most suitable way to effectively protect the ancient and rare trees involved in the project. Conclusions have reference value to similar projects.

中药调剂工作的改革思路

世界科学技术-中医药现代化 , 1999,
Abstract: 本文提出用开水泡服经过精制且用量少的中药饮片或颗粒而获得同样的甚至更高的疗效 ,既方便又节省。通过对中药饮片的开水浸出液与汤剂的比较 ,以及现有袋泡剂的应用情况 ,探讨了这种想法的可行性及对饮片加工和调配工作的改革思路
Conditions for Counties under the Direct Provincial Administration :A Study of 26 Provinces and Autonomous Regions in China
省管县的条件及对我国26个省区的聚类研究


浙江大学学报(人文社会科学版) , 2010,
Abstract: The system reform of counties under the direct provincial administration (CUDPA) has now become an important aspect of Chinese local administrative reform . Conditions for CUDPA could be listed as follows : A common understanding of the importance of reform , an appropriate scope of administration , a necessary economic foundation , a good technological guarantee , and the sufficient experience in experiments .SPSS was used in this study to process factors of the area size ,numbers of counties and cities ,per capita GDP ,index of marketization , level of electronic government , density of freeway , proportion of counties whose powers are expanded , months from the time of expanding powers ,26 provinces and autonomous regions can be classified into six types .In the process of reform , provinces with ripe conditions should take the lead ,setting examples for the others tofollow .Provinces whose conditions are not ripe should try their best to create conditions whereas for those provinces without right conditions will have to wait for a suitable time .

布朗意──蒙索盆地煤相研究

沉积学报 , 1994,
Abstract: 本文以布郎意-蒙索盆地厚度达40m的第一煤层为单元,根据煤样光片光泽、色彩及组构划分出八类煤相。用有机岩石学方法及热解分析法详细研究了这些煤相。结果表明该煤层主要为微异地-异地沉积,生源输入以木本植物为主;煤层内部也存在类似煤系地层那样的旋回沉积,其原因推测为泥炭非均一性引起差异压缩;煤相的变化主要由水动力条件及水平面高低引起.这种变化明显影响了显微组合的物理一化学性质,如镜质体反射率、孢子体荧光及煤相的氢指数。该研究还指出了各种沉积环境标志物的可靠性。关键词
麦田蒸腾需水量的计算模式
谢贤,
地理学报 , 1997, DOI: 10.11821/xb199706006
Abstract: 本文依据Penman-Monteith方法对小麦田田间蒸腾需水量计算方法进行了探讨,得出了一个改进的小麦蒸腾需水量计算模式,对模式中某些参数作了修订;并用中国科学院禹城综合试验站的观测资料对模式进行了计算,结果表明,采用本模式计算充分湿润麦田的蒸腾需水量效果良好
基于运输需求的基础路网规划理论与方法研究
虎啸,
公路交通科技 , 2010,
Abstract: 为了解决中国公路运输的"瓶颈"问题,使运输更好地为国民经济服务,提出了基础路网的概念,分析了现有公路网的干线路网和基础路网的范畴,研究了运输需求与交通需求在作为路网规划的变量时的区别以及运输需求对基础路网布局规划的影响。以有利于国民经济和社会发展产生的运输需求为目标,构造了基础路网规划的模型和算法。规划模型以投资费用最小为前提,为缩短路网建设里程,节约建设成本,增加了费马点,并证明了该方法是有效的。开发了模型与算法的集成软件ArcGIS,使得整个规划过程的计算与分析数据化,结果可视化,并对模型和算法的效果进行了验证。分析结果表明规划后的基础路网使用效率能相对保持在70%~80%这一理想范围内,能够清楚地反映研究区域运输需求的要素。因此,基于运输需求来规划基础路网可行。
