The time period of the study of urban land use is 1990s . on the analysis of the scale expansion feature and the feature in evolution of land use structure , the paper points out the rationality and existing problem in the evolution of urban land use . the paper may provide reference value for sustainable use of urban land and city development in the future 城市土地利用研究的时间段是20世纪90年代，通过对城市土地利用的规模扩展特征及用地结构演变的特征进行了分析，指出了城市土地利用演变的合理性与存在的问题，为今后城市土地的可持续利用与城市发展提供了一些参考价值。
With the guidance of human geographical basal theory and thoughtway , this article use for reference fruits of industrial economics , city economics , regional economics etc , gets across practical investigating , analyzing the structural evolvement of regional industry , urbanization , as well as power factors of mutual action , elemental character , evolve mechanism , regional types and founding model on urbanization response of structural evolvement of regional industry . according to the character and problems existing in the extent , put forward urbanization ’ s response mode and countermeasure of structural evolvement of regional industry in jiaozuo city by quantitative and correlation analysis 本文通过实地调查,在人文地理学基本理论和思维方法的指导下,充分运用和借鉴产业经济学、城市经济学、区域经济学等相关学科理论及已有研究成果,通过分析区域产业结构演变与城市化互动机制、作用要素、地域类型等,建立了焦作市产业结构演变的城市化响应回归模型,并进行了定量相关分析,根据其表现出的特征和存在的问题,提出了焦作市产业结构演变的城市化响应模式及相应对策。
Statistically , it makes a quantitive analysis on the evolvement of the country economic structure in xi ' an city , the economic benefit of the changes in industry structure , the effect on labor resource collacation in industry structure and the effect of the increasing income of countrymen in industry structure changes , which discloses a rule of the industry structure evolvement in country . the putting forward of the non - agriculture industry in country , especially the rapid increase in country industry will promote the rise of the country industry level for a long term . the country industry structure influences a lot the increase of the farmer ' s income which is also affected by agriculture structure and planting structure , but less . the non - agriculture industry plays a main role in the increase of farmer ' s income . for the low level of the townlization and industrialization , developing industry , construction and commercial in country is very feasible to resolve the problem of spare labors in country . it is strengthening labors transferring and reducing the modulus of labor over the infield that farmers income could be kept increasing . after a theoretical analysis and twenty years practise in the regulation of country economy structure after the reform and opening policy in xi ' an , a new thought of regulating country economy structure in xi ' an is put forward that a strategic regulation must be taken in country economy structure and the agriculture structure must be optimized . moreover , an expanding agriculture must be developed and transfer the spare labors in country effectively . so the government function during the regulation of country economy structure is transferred to : the first one , making the stress policy in the regulation of country industry structure . 2ndly , strengthening the force in regulating country industry structure ; 3rdly , making a plan on the regulation of country industry structure ; 4th promoting the optimizition and upgree of industry relying on sci - tech progress ; 5th enhancing the townlization and optimizing the country industry structure ; last one , improving the quality of labors in full scale 本文在概述经济结构理论的基础上，第一次系统地研究了西安市农村经济结构调整，用数据统计的方法，定量、定性地分析了西安市农村经济结构演变的轨迹，分析了产业结构变动的经济效益、产业结构劳动力资源配置效应、产业结构变动的农民收入增长效应，揭示了农村产业结构演变的规律。提出农村非农产业，尤其是高速增长的农村工业，对促进农村产业水平的提升起着长?推动力的作用；农民收入增长直接受农村产业结构的影响最大，农业产业结构、种植业结构对农民收入有影响，但作用不可高估；非农产业是农民增收的主要支撑力量，解决农村余劳动力在城镇化、工业化水平不高的情况下，切实可行的选择是在农村发展工业、建筑业、商饮业等非农产业；农民收入要保持快速增长态势必须加大农村劳动力转移力度，减少耕地承载劳动力的系数。通过理论分析，结合西安市改革开放后20多年的农村产业结构调整的实践，提出了西安市农村产业结构调整的发展思路及目标、原则，明确指出了政府在农村经济结构调整过程中的职能转变的重要方面：一是制定农村产业结构调整的倾斜政策，二是加大对农村产业调整的投入力度，三是制定产业结构调整的规划，四是依靠科技进步促进产业优化和升级，五是加快城镇化过程，优化农村产业结构。
Variation of tourism structure is basic fact in the course of evolution , among which , evolution of tourism product structure is more paid attention to , tourist market structure is dimension of tourism product need , variation of residents " perception and attitude is a reflection of evolution of tourism product structure in sociology 旅游结构的动态变化是演进过程中的基本事实，其中旅游产品结构的演变愈受关注，旅游市场结构是旅游产品的需求层面，居民感知态度变化是旅游产品结构演变在社会学的一种体现。
This paper is based on the history of community governance in the developed countries , the author focuses the structure of community governance the mature phase in western countries , studies the process of the transformation in the community building from management to governance , analyzes the reasons and results and support the countermeasures . the author suggests optimizing the structure of community governance must reach the highest level of the city government , let government work together with the main bodies of marketplace and community , by this way , realize the " good governance " and restructure the social capital 本文在对西方国家社区治理结构演变历程和成熟阶段的社区治理机制探讨的基础上，研究了中国社区建设由社区管理向社区治理转型的相关内容，分析了中国“社区治理失灵”产生的原因、后果，提出了矫正对策，指明中国社区治理结构的优化必须触及城市最高权威体系，使其由社区建设的管理者变为合作者，最终在社区建设上实现“善治”和重建社会资本。
Analyse the research of distributing of microbe community and the tendency of the change , disscuss the principle and traits of denaturing gradient gel electrophoresisand terminal restriction fragment length polymorphism , to research the law of change that the microbe community have in composting process , we can get effective and rapid information to filtrate the microorganism during composting process , then accelerate the development of compost technology 摘要对堆肥微生物种群分布及其动态变化的研究进行了分析，论述了分子生物技术中的变性梯度凝胶电泳和末端标记限制性片段长度多态性的原理和特点，以及用于研究堆肥微生物的群落结构演变规律，为分析和筛选堆肥中的微生物提供更加有效、快速的信息，促进堆肥技术的发展。
