浅谈农村住宅拆迁的调产安置模式     

徐盛馨  谢建定  黄绍华  宋培华 《浙江地质》2009,(7):30-33

随着城市规模的不断扩大和城镇化程度的不断提高,大量的农村住宅被拆迁。近年来,依据土地节约集约利用的原则及其本身的特点,调产安置逐渐成为当前农村住宅拆迁安置的主要模式。认真研究和分析调产安置的优点和弊端,对于进一步做好今后的农村住宅用房的拆迁安置工作与提升土地利用效率具有重要的现实指导意义。笔者结合自身工作实际,就农村住宅用房拆迁调产安置谈些自己的看法。  相似文献   

透视征地群访事件     

谢建定 《浙江地质》2009,(12)

近年来,随着我市经济的发展与城市的扩张,各地征地所带来社会问题和引发的矛盾愈发凸显出来。征地引起的上访乃至于群体事件层出不穷,动辄几百人闹事的恶性事件也不鲜见。其中因征地引起的矛盾和纠纷的日益激烈表明,征地问题已不再是表面上的城市建设纠  相似文献   

一类球谐函数与三角函数乘积积分的计算   总被引：3，自引：0，他引：3  

吴星  张传定 《测绘科学》2004,29(6):54-57

本文根据球谐函数的跨次递推公式和三角函数的性质,详细推导了在重力梯度调和分析中出现的一类球谐函数积分的跨次递推公式和递推初始值的计算公式。数值试验表明,球谐函数跨次递推算法具有快速、稳定的优点。该类积分的跨次递推实现,为卫星重力梯度调和分析奠定了算法基础。  相似文献

马玉宏  赵桂峰  王焕定 《地震工程与工程振动》2004,24(5):79-83

首先,在简述已有隔震体系抗震设计方法的基础上,分析了滞变一摩擦隔震体系各种因素对基底剪力的影响;然后,通过大量仿真分析,采用多项式回归的方法提出了与规范衔接的水平地震作用的计算公式;最后,提出了梯队式变刚度滞变一摩擦隔震体系的抗震设计方法,并通过工程实例验证了方法的有效性。  相似文献   

隔震换能结构体系的能量分析   总被引：6，自引：0，他引：6  

程树良  孙作玉  王焕定 《地震工程与工程振动》2004,24(3):179-184

将换能器安装在隔震结构的隔震层处,由结构和换能装置构成隔震换能结构体系,它既可以将地震输入给结构的部分能量转换成液压能,实现地震能量的转换,又能减小隔震层的水平位移,降低对隔震层的技术要求,降低造价。本文详细研究地震输给隔震换能结构体系的能量在体系各部分的分配,并与普通隔震结构对比,从能量的角度揭示隔震换能体系的换能控制原理。  相似文献   

宁波市土地征收补偿安置政策研究   总被引：1，自引：0，他引：1  

李千火  陈叶红  谢建定 《浙江国土资源》2013,(1):40-42

根据党的十八大精神指示提出改革征地制度．让农民分享土地增值收益的要求,新土地管理法和土地征收条例即将修改出台,改革的路径选择主要是提高征地补偿标准,加大保障被征地农民利益的力度,新征地补偿安置政策出台直接关系到社会发展与稳定,将对我市新一轮建设带来新的影响。在充分肯定我市现行征地补偿安置政策为全市重大项目、新农村改造、城市城镇建设有力推进起到了非常积极作用的同时,应该充分认识到如何紧紧围绕新国土地征收制度改革要求,  相似文献   

东海三叶原甲藻的形态特征及其ITS序列分析     

王红霞  陆斗定  何飘霞  夏平  戴鑫烽 《海洋学报(英文版)》2012,31(4):155-162

报道了首次分离于东海海域的三叶原甲藻(Prorocentrum triestinum Schiller)藻株号(LAMB100721),通过利用光学显微镜、荧光显微镜、扫描电镜及分子生物学方法,对其形态特征、显微结构和分子系统进化进行了详尽描述和鉴定。细胞长卵形或披针形,后端细长且尖,前端圆,最宽部位于细胞中央。顶刺长而显,三角状。壳面光滑,无刺或突起物。刺丝胞孔稀疏而不规则地分布于壳面边缘。叶绿体无具体形状,分布于整个细胞中,细胞核球形,位于中下部。老化的细胞可见细胞边缘的间接带,且间接带表面光滑。细胞长为19~25 μm,平均值为(22.6±0.9)μm;宽为11~16 μm,平均值为(13.2±1.1) μm。所测目标藻株的rDNA ITS序列长度为569 bp,其中GC含量为47.6%。三叶原甲藻系赤潮种,为东海原甲藻春季大规模赤潮的伴随种。加强有害赤潮的预防和监测工作是减少危害的有效途径,而对赤潮原因种的准确识别和鉴定则是基础和关键。  相似文献

Identification of two Skeletonema costatum-like diatoms by fluorescence in situ hybridization     

张宝玉  陈国福  王广策  陆斗定 《中国海洋湖沼学报》2010,(2)

A harmful algae bloom (HAB) is a dense aggregation of algae in a marine or aquatic environment that can result in significant environmental problems. To forecast the occurrence of HAB, development of a rapid and precise detection method is urgently required. In this study, two Skeletonema costatum-like diatoms (SK-1 and SK-2), were identified morphologically under a light microscope, and detected using fluorescent in situ hybridization (FISH). Strain SK-1 was isolated from a frequently HAB affected area of the East China Sea, and strain SK-2 from an aquatic farm in Qingdao, China. Fluorescent DNA probes were designed that were complementary to the ITS sequence (including 5.8S rDNA) of strain SK-1. After hybridization, strong green fluorescence was observed in cells of strain SK-1 under an epifluorescence microscope; however, no such fluorescence was observed with strain SK-2, which indicates that probes hybridized only the DNA of the target strain, SK-1, in species-specific manner, and that the two strains do not belong to a same species. This finding was confirmed by ITS sequence analysis. The FISH technique used in this study was sensitive, simple, and rapid, and is a promising tool for detecting target HAB species in natural environments.  相似文献
