成都统筹城乡改革所涉及的方面较多,文章围绕统筹城乡改革重点内容的权利倾斜性配置,从土地流转、户籍改革、就业和社会保障出发,对成都统筹城乡改革中权利倾斜性配置相关对策行为与未预期后果进行分析。针对改革中存在的道德风险、生存风险及效率问题,找出在此过程影响权利倾斜性配置的关联主体、改革周期、利益保护方式等因素。最后,针对上述分析,结合利益关联主体的种类、利益关联者的对策行为、各级政府的干预困境进行梳理,以期避免在改革中出现一味倾斜于农村居民的权利配置方式。  相似文献

重庆被确定为统筹城乡改革试验区后,农村土地流转速度加快,这为重庆农业产业结构调整、城镇化、城乡一体化和城乡统筹发展,起到了助推剂的作用。但作为三农问题核心的农村土地问题,重庆农村土地流转仍面临诸多问题,必须建立完善土地流转政策法律体系,健全土地流转的市场机制,做好农民权益的保护,通过土地使用权流转推动城乡统筹发展。  相似文献

土地整治在城乡统筹发展中的支撑作用日益凸显.以刘易斯经济增长的通道说为视角,分析土地整治与城乡统筹之间的关系,研究表明:城乡统筹和土地整治分属于两者关系的需求导向面和供给调整面,发挥土地整治对城乡统筹的支撑,必须搭建城乡统筹发展的土地整治"有形"和"无形"通道,而与"通道"相契合的关键环节和落脚点,是土地整治促进城乡统筹发展的实践载体和具体抓手.重庆土地整治在促进城乡统筹发展方面取得了实效,其经验证实,土地整治促进城乡统筹发展的关键是利用"有形"与"无形"通道,抓住关键环节和落脚点实施"人地分离"的农地集中连片整治和"地随人走"的农村建设用地整治,以便对土地及其附属资源要素进行有效整合.  相似文献

地价是地租的资本化,是土地权利与其预期收益的购买价格,是土地市场运作的重要信息和价值判断标准.地价指数作为地价的量化,能反映一定区域内地价变化趋势及程度,具有重要的研究价值.本文以地价指数为研究对象,针对目前研究中存在的指标选取不详尽、作用机制不明确和数学模型建立不完善等问题,将经济学中的“供需关系”概念引入地理学研究,在对数据进行标准化处理的基础上,进行了主成分分析和平稳协整分析,建立了多元协整滞后回归模型,分析了不同层次、不同地区、不同用地类型下影响地价的因素及其滞后性,研究发现京津冀三地地价分别主要受社会经济等状态、土地供给和土地需求的影响;三地地价受自身历史数据的影响均大于指标历史数据的影响.  相似文献

随着我国经济发展、社会进步、城市与乡村逐渐有一体化倾向。实现城市化需要从土地制度改革作为突破口。本文以湖南宁远县为例,通过文献资料法和调查法,研究得出:可采取土地置换促进城市的可持续发展,保障农民利益;通过城市化,废除城乡界限,推动中国特色社会主义道路前进。表明正确处理城乡统筹建设与土地制度改革可优化资源配置,实现城乡共同繁荣,促进和谐社会建设。  相似文献

减少土地估价过程中的人为主观性对于提高土地估价的科学性和客观性具有重大意义。以南昌市主城区为研究区,选取100多个住宅用地交易案例为样本,运用BP神经网络和GIS空间分析方法,分析住宅地价及其影响因子之间的复杂关系,构建BP网络建立地价与影响因子之间非线性映射关系并进行地价预测。研究结果表明:商业因素、公共设施因素、交通因素和环境因素对住宅地价有显著的影响;用BP神经网络对地价的预测误差均控制合理范围以内,BP神经网络强大的非线性映射能力和自主网络学习,理论上可以实现对住宅地价的评估,为政府和经济主体参与经济活动提供科学的依据。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  相似文献

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3~4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰~ -7.8‰, PDB) and matrix dolomites (-6.6‰~ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084~0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078~0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.  相似文献

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

Quality traits in wheat (Triticum aestirum L.) were studied by quantitative trait locus (QTL) analysis in a recombinant inbred line (RIL) population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross (ChSh). Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献
