Through detailed analyzing some influencing factiors of sand liquefaction, seven parameters were selected as assessment indexes. They are earthquake magnitude, peak ground surface acceleration, standard penetration value, specific penetration resistance, relative compaction, average particle diameter, and water table. The extension assessment model has been established that was applied to assessment of sand liquefaction potential. The model had been trained by the historical data and has been assessed in virtue of sand liquefaction from the historical data by simulating, and got a excellent result. After introduction of the support vector machine theory, this paper established the assessment model of sand liquefaction based on the support vector machine, and assessed in sand liquefaction from virtue data of some fields in home and overseas with the tool Libsvm, which was programmed based on the support vector machine theory. And got a good coherency between the assessement results and the actual liquefaction.

在详细分析影响砂土液化因素的基础上，选取了震级M、地面最大加速度g_、标准贯入击数N_(63.5)、比贯入阻力P_s、相对密实度D_r、平均粒径D_(50)、地下水位d_w等7个参数作为评价指标，建立了砂土液化势的可拓评价模型，并对历史数据进行仿真评价，取得了较好的应用效果；在对支持向量机的理论进行介绍后，本文建立了基于支持向量机的砂土液化势评价模型，并利用在基于支持向量机理论的Libsvm软件，对若干国内外场地的现场实测数据进行了评价，评价结果与现场表现基本上一致。

The index system was first set up, which reflected the economy, society, resources and environment conditions in the district. Then, factorization method was employed by using the software SPSS to obtain comprehensive index numbers. The linear regression method and fuzzy mathematics method were used to compute the coordination degree of economy, society, resources and environment. Finally, on the basis of the status of comprehensive evaluation indexes and coordination degree of the district, the main problems in the sustainable development of Beibei District were found out and some suggestions were also proposed.

为将北碚建设成为国家可持续发展示范区，探讨有北碚特色的可持续发展模式，首先建立反映北碚区经济、社会和资源环境发展状况的指标体系；在此基础上，利用SPSS软件对数据进行因子分析，得到三大体系的综合评价指数；将综合评价指数代入eview软件选择适合的回归方程，再利用模糊数学的方法，计算出成立试验区以来北碚的经济、社会和资源环境的协调发展度；最后在综合评价指数和协调度的基础上，发现北碚区协调发展的主要问题并给出建议。

The frame of index systems were set up, and the index systems for evaluation of the abilities of agriculture sustainable development in Guangdong were given according to the concept of agriculture sustainable development, and the principle of constructing index systems for evaluation of the abilities of agriculture sustainable development in this study.

This text has studied the historical origin and realistic background of the sustainable development thought; has narrated current situation and trend of domestic and international sustainable development research; has provided the definition of regional sustainable development on the foundation of analyzing constant concept; has stressed the rationality, systematicness and practicality of sustainable development; has set up the conceptual model of regional sustainable development, structured the regional sustainable development evaluation index system frame and appraise models; has studied the judge base of regional sustainable development.

本文探讨了可持续发展思想的历史渊源和现实背景，综述了国内外可持续发展研究现状和趋势；在剖析可持续性概念的基础上探讨了区域可持续发展的定义，突出了可持续发展的区域性、系统性和实践性；建立了区域可持续发展的概念模型，构建了区域可持续发展评价指标体系框架和评价模型，探索了区域可持续发展的判断依据。

The aims of disaster study and risk study are tent to unanimousness, both will offer the theoretical basis for sustainable development models. Regional safety construction based on disaster study is converting into regional risk management system based on risk study. So the authors consider that sustainable development model is the regional development model under a certain risk level, and the risk level relies on the regional safety construction level that integrates the regional economic level and social cultural system. Strengthening subject construction of disaster and risk study in China, national laboratory construction, and organization and practice of key items are imperative. And we should put the study emphasis on the vulnerability assessment system and models, risk assessment system and models, disaster and risk management mode of typical region, disaster and risk emergency control scenario, disaster and risk regions.

灾害与风险研究的目标正在趋向一致，都集中在为可持续发展模式提供科学依据；基于灾害研究的区域安全建设正在向基于风险研究的区域风险管理体系转变，由此认为可持续发展模式就是接受一定风险水平条件下的区域发展模式，一定风险水平依赖于由区域经济水平与社会文化体系相关联的区域安全建设水平；加强我国灾害与风险科学研究的学科建设、国家实验室建设、重大项目的组织与实施已势在必行；重点开展灾害脆弱性评价体系与评价模型、风险评价体系与风险评价模型、典型区域灾害与风险管理范式、灾害与风险应急控制预案、灾害与风险区划等方面的研究。

Based on the current state of the evaluation of sustainable utilization of water resources,this paper summarize and expect contrastively the representative evaluating methods used in common,offer reference on choosing the evaluating methods of sustainable utilization of water resources.

Based on the theories of sustainable development,index system of forest resources sustainable management and comprehensive evaluation of urban forest,the index system of measure the urban forest sustainable development have been put forward.

在可持续发展理论、森林资源可持续经营指标体系研究及城市森林综合评价指标体系研究的基础上，提出衡量城市森林可持续发展的指标体系框架，设计城市森林可持续发展的综合评价方法。

Consequently, to evaluate forest sustainability of a certain region becomes important in sustainable forestry and sustainable development. Forest carrying capacity is an important and key index in evaluating forest sustainability, premise of forest management and decision-making, and an essential component of the theories in sustainable forestry and forest management and forest ecosystem.

因此，如何评价一个确定区域的森林是否可持续便成为可持续林业、可持续发展研究中亟待解决的重要问题，而森林承载力是森林可持续性评价中的一个重要的关键的指标，是制定和实施区域可持续林业发展规划、战略的前提，是区域森林经营管理决策的依据，同时它也是可持续林业理论的重要组成部分，是森林经营管理理论和森林生态学中的一个全新内容。

Methods 37patients with complicated dentition defect that can't use traditional removable partial denture were involved in the study.

选择37例因传统可摘局部义齿无法戴用或对此类修复体效果不满意的复杂牙列缺损患者，附着体义齿修复前首先请患者对现有可摘局部义齿就咀嚼功能恢复、舒适度、发音与美观3个主观项目进行评价，其次由修复科医师对义齿的固位情况、对基牙的影响、对口腔卫生的影响3项客观指标进行评价，并在附着体义齿修复后1～5年再对上述6项指标进行评价。
