中国农村宅基地整理潜力估算

由于土地利用分类中缺乏农村宅基地的用地类型,中国目前尚缺乏全国尺度的农村宅基地整理潜力估算结果,不利于农村宅基地整治工作的开展和部署。笔者建立了依据农村居民点整理潜力推算法、户均宅基地标准法和农村人口等比例缩减法3种方法,估算了中国2020年的农村宅基地整理潜力。研究表明：（1）2020年,依据农村居民点整理潜力推算法测算的宅基地整理潜为239.05×104 hm²,户均宅基地标准法的测算结果为597.50×104 hm²,农村人口等比例缩减法的测算结果为130.36×104 hm²;（2）户均宅基地标准法测算的农村宅基地整理潜力由于缺乏对农村宅基地整理中自然、经济、社会限制性因素的考虑而明显偏大,综合修整后,该方法测算的中国农村宅基地整理潜力约为191.20×104 hm²;（3）统筹考虑各种测算方法的结果,中国2020年的农村宅基地整理潜力约为200×104 hm²。空间上,中国农村宅基地的整理潜力主要分布在东部和中部区域;相对而言,东北区和西部地区的整理潜力较小。各省份中,山东、安徽、河南、江苏、辽宁、黑龙江等省份的整理潜力较大;西藏、青海、上海、福建、海南5个省份的整理潜力较小。     

The Causes of the Difference between Supply and Demand in the Housing Market of China and Solutio ns to the Problem

The reason for the difference between supply and demand of houses is that there is a non equilibrium in the interests of purchaser, developer and the government. In order to solve this problem, the developer should cut down the cost, the purchaser should clarify the house value and the government should build up a house property evaluation system to improve the housing market.     

A Study on Evaluation of Economy of Commodity Housing

The housing industry, as a new economy growth point and hot point of consumption in our national economy, has huge potentials for its development. Because of the underdevelopment of the commodity housing market in our country, there are some unhealthy tendencies, such as low level of development, poor quality of housing, waste of resources, large deviation between housing function and its price, and so on. So there is urgent need to take measures for avoiding these unhealthy phenomena. It is one of the strongest measures to evaluate the economy of the commodity housing. In this paper the meaning, principle and method of the evaluation on economy of the commodity housing were discussed. It will play a positive role to promote spreading this work.

基于AHP城市保障房用地空间分布研究

为了使保障性住房用地的空间布局更加科学合理,中低收入群体的住房需求能够得到充分保障。本研究通过对河北省11个地级市独立性保障房用地现状进行调查,选取距市中心距离和基准地价水平两个因素,并分别以相对距离指数和相对级别指数建立各市可比基础,运用AHP模型,设定3级评价尺度,对各市保障性住房的区位优劣度进行定量评价。结果表明河北省各市保障房建设情况总体较为均衡,张家口、唐山、石家庄在保障房选址上较其他城市更为合理,并深入分析现阶段保障房用地分布相对理想的原因,建议从立法规范、居住模式、转变观念、丰富房源等角度进行优化。

     

An improved dynamic model of transformer hotspot temperature based on top oil temperature

The winding hot spot temperature of the oil immersed power transformer is an important parameter. It has a great influence on the transformer insulation aging and a close relationship with the transformer top oil temperature. The changes of non linear thermal resistance, open circuit impedance, and oil viscosity and winding losses with temperature are also taken into account. An improved model added on the transformer top oil temperature to calculate transformer winding hot spot temperature by using the viscosity and loss correction factors is proposed. Model parameters are estimated by Levenberg Marquardt method. In the end, by comparing with the measured data tested under different conditions, the model shows good consistency under underload (90%), rated load (100%) and overload (110%) conditions respectively, and describes the temperature variation more accurately in the dynamic loading profiles.

不同生态点对棉株主要农艺及经济性状影响的研究

不同生态条件下,麦克隆值与单株成铃的变异系数最大。关联分析结果表明,2.5％跨长是制约气纱品质与整齐度的主导因素,整齐度是制约2.5％跨长与比强度的主导因素,2.5％跨长与产量的变化趋势接近。在产量构成因素中衣分是制约单株成铃、单铃重、衣指的主导因素,衣指是制约衣分的主导因素,而单铃重是制约子指的主导因素。通径分析结果表明,2.5％跨长与衣分对产量的综合直接作用最大。主成分分析表明,在湖南特定的环境条件与栽培条件下单株成铃、单铃重、衣分三者的信息量仅占总信息量的82.66％;2.5％跨长、麦克隆值、比强度三者的信息量占产量总信息量的66.89％。     

硒对小麦生理功能的影响之研究进展

硒是小麦生长所必需的微量元素。硒在小麦体内通过吸收转化,能够促进小麦新陈代谢,增强小麦生物抗氧化作用和对环境胁迫的抗性,从而刺激生长发育、提高产量、改善品质。通过施入外源硒肥的方式增加小麦中的硒含量,使硒进入食物链,是为人体安全补硒的有效途经。从上述几方面综述了硒在小麦中的生理功能及富硒小麦的研究进展。

西部地区农户金融需求与农村金融供给--菜园村与纸沟村农村金融调查报告

以西部地区两个农村社区作为案例调查对象，试图了解西部地区农户金融需求与农村金融供给的一般状况。两村调研结果表明，农户金融需求非常强烈，而农村正规金融供给存在区域差异性，资金有限，品种单一，不能充分满足广大农户的资金需求。在这种情况下．农户从非正规金融途径的融资活动就非常普遍。从用途上讲，正规金融贷款主要用于农户生产性投入．农户的生活性支出主要依靠非正规金融供给，即私人信贷。
