Land suitability evaluation for development using a matter-element model: A case study in Zengcheng, Guangzhou, China

Land suitability evaluation can assist in the efficient use of land resources at a regional level. This is an important issue because of the pressures that an increasing population and economic growth have put on limited land resources. Matter-element theory, which was first put forward by the Chinese mathematician Cai Wen, has shown potential for solving incompatibility problems. Based on the matter-element model, this paper uses land use, roads, water bodies, population density, distance from center of the city, geodetic height, and slope as factors in modeling land suitability for development. Zengcheng, an urban-rural administration was used as a case study for applying the matter-element model to assessing the suitability of land for development. The model was cross referenced with local urban plans for verification and the results of this study show that the model constructed was effective at assessing the suitability of land for development. According to both the classification map created using the matter-element model and the statistics on the of land suitability classes, the study area was found to have a considerable amount of land which is highly suitable for development. After the category ‘highly suitable’, the next largest total land area was in the category of ‘not suitable’ for development, while there was relatively little land classified as moderately and marginally suitable. The percentage of the total land area of each class of suitability was 41.80%, 34.22%, 16.35% and 7.64%, respectively. Apart from this, the study also demonstrated the advantage of matter-element models over fuzzy theory, as they provide much more information. For example, all integrated degree of all classes in the paper had ranges from −1 to 1, but differed from each other by percentage. In the category of ‘highly suitable’ only 45.51% of matter-elements fully conformed to the criteria (those within a range of 0-0.5925), while the remainder (54.49%) did not corresponded to the requirements of the category, but did have the potential to do so with relatively few changes (those within a range of −0.3923-0 degrees). This data provides us with an understanding of the potential and limitation to development of the land in the region.     

战略型“订单粮食”模式探讨

地勘单位探采一体化的政策研究

地勘单位探采一体化是近年来学术界持续升温的热点话题。一些业内人士认为,地勘行业、地勘单位探采一体化似乎天经地义,理所当然,因为地勘单位是距离采矿最近的行业,采矿是地质勘查找矿的自然甚至必然的延伸。实际上,我们必须找准角度,分析国家和地方政府为什么没有明确给予地勘单位探采一体化政策,通过政策和地勘单位性质方面的研究,尽可能找出和提前应对各方面的困难和问题,合理调配和优化企业化经营的要素,做好企业化改制和探采一体化等各方面的准备。     

元认知策略培训对学生英语阅读学习效果影响的实证研究

学习者的元认知就是对如何学习一门语言的自我认识与自我反省。元认知策略是元认知的组成部分,是学习者为了成功学习一门外语所采取的管理措施。在现行的大学英语课堂上进行系统的元认知策略训练与指导是提高教学效果的有效途径,对于纠正学生不恰当的英语学习方法和策略,提高语言学习的信心与兴趣,提高自主学习能力等方面起着极其重要的作用。

集体声誉下最低质量标准的福利效应

本文针对集体声誉行业的特点构建两阶段博弈模型,从竞争效应和质量效应两个方面系统考察了集体声誉下最低质量标准规制的福利效应.结果发现,最低质量标准通常具有的反竞争效应在集体声誉行业并不存在,适度并偏高的标准在提高质量水平的同时反而会增加行业当中的企业数量和改善社会福利.最后,结合我国乳品新国标的例子,对运用最低质量标准规制解决我国集体声誉行业普遍存在的质量问题提出了政策建议
