A multi-mutualist simulation: Applying biological market models to diverse mycorrhizal communities

We present a cellular automaton that simulates the interaction between a host tree and multiple potential mycorrhizal symbionts and generates testable hypotheses of how processes at the scale of individual root tips may explain mycorrhizal community composition. Existing theoretical biological market models imply that a single host is able to interact with and select from multiple symbionts to organize an optimal symbiont community. When evaluating the tree–symbiont interaction, two scales must be considered simultaneously: the scale of the entire host plant at which carbon utilization and nutrient demands operate, and the scale of the individual root tip, at which colonization and carbon-nutrient trade occurs. Three strategies that may be employed by the host tree for optimizing carbon use and nutrient acquisition through mycorrhizal symbiont communities are simulated: (1) carbon pool adjustment, in which the plant controls only the total amount of carbon to be distributed uniformly throughout the root system, (2) symbiont selection, wherein the plant opts either for or against the interaction at each fine root tip, and (3) selective carbon allocation, wherein the plant adjusts the amount of carbon allocated to each root tip based on the cost of nutrients. Strategies were tested over various nutrient availabilities (the amount of inorganically and organically bound nutrients). Success was defined on the basis of minimizing carbon expended for nutrient acquisition because this would allow more carbon to be utilized for growth and reproduction. In all cases, the symbiont selection and selective carbon allocation strategies were able to meet the nutritional requirements of the plant, but did not necessarily optimize carbon use. The carbon pool adjustment strategy is the only strategy that does not operate at the individual root tip scale, and the strategy was not successful when inorganic nutrients were scarce since there is no mechanism to exclude suboptimal symbionts. The combination of the symbiont selection strategy and the carbon pool adjustment resulted in optimal carbon use and nutrient acquisition under all environmental conditions but result in monospecific symbiont assemblages. On the other hand, the selective carbon allocation strategy is the only strategy that maintained successful, multi-symbiont communities. The simulations presented here thus imply clear hypotheses about the effect of nutrient availability on symbiont selection and mycorrhizal community richness and composition.

城市群竞争与共生的时空机理分析

城市群演化是一个竞争与共生相互作用的过程,竞争是指在城市群内的各个城市在共同发展中为获取有利的发展地位和发展条件而进行的角逐,而共生是指群体发展中的统一规划和相互依存、相互支持的关系。城市共生关系的根本内涵和特征是空间上的临近性、时间上的长期性、功能上的分工互补性、个体之间的差异依赖性以及作用关系的支持协调性。依据系统论的原理,提出竞争与共生作用可以划分为弱竞争弱共生、强竞争弱共生、强竞争强共生、弱竞争强共生4个发展阶段,并呈现周期性特征,这从城市与区域的演化中都找到了实证。并将城市群竞争共生作用划分为群内竞争与共生、群外竞争与共生、群内竞争与群外共生、群外竞争与群内竞争4个空间作用层面,初步总结出竞争共生作用的一般模式。     

Analysis of the Difference of the Basic Pension by Regions

Abstract

Nowadays, the disparity of the basic pension in local regions of China can be described as follows: the low level of the unification of the basic pension systems, the large disparity of the level of the basic pension, and unfairness of the enterprises' payment for the basic pension in different local regions in China. These have already brought many negative influences, which have greatly held back the development of the society and national economy. We should build the basic pension system in all local regions of China as a whole, which can cover all people and decrease the disparity in different local regions in China.     

我国环境政策中生态工业园内涵误区的分析

作为一种新的工业可持续发展方式,生态工业园已经在世界范围内得到广泛应用。在我国,随着近几年生态工业园建设的蓬勃开展,出现了一些认识和实践中的误区,这些误区可能会影响我国循环经济下一步实践的顺利开展。文章以生态工业园概念的内涵为主线,通过系统梳理和分析相关的国内外文献和我国的法规政策,首先总结了生态工业园的广义和狭义内涵,提炼了工业共生的目标要素、主体要素和行为要素;其次分析了工业共生与循环经济、清洁生产之间的相互关系;在此基础上,提出了目前生态工业园实践中出现的"循环经济式、污染控制式、产业发展式"三种内涵误区,并进一步剖析了我国政策制定过程中的两个深层问题,即生态工业园实践内容的简单组合化和生态工业园目标与内容的脱节。     

和谐视域中农村五保老人的社会保护——来自湖南省农村五保养老问题的实证研究

五保老人是当前农村最特殊、最困难的群体。对他们的救济是我国社会保障事业的重要内容。五保，其供养工作是保障困难人群基本权益、促进社会和谐的重要机制之一。是建设和谐社会的需要。对湖南部分农村的调研发现：五保老人物质供应不足、其他社会权利受到漠视．具有“孤、老、病、贫、弱”等脆弱性特质。必须把对五保老人的社会保护提升到人权保障的层次，由政府承担第一责任人义务．通过构建完善的五保老人供养制度体系确保他们晚年的和谐生活。并在保障物质需求的基础上扩充和保护其他社会权利。     

新质生产力的科学内涵与绿色发展

发展新质生产力是新时期推动高质量发展和美丽中国建设的内在要求和重要着力点。本文从新质生产力的科学内涵出发,探究了新质生产力与绿色生产力之间的理论逻辑。新质生产力是一种更先进的生产力质态,体现为劳动者素质提高、劳动资料改进、劳动对象拓展、科学技术进步和管理效能提升,即经济学视角中人造资本、人力资本、生态资源等不同生产要素的配置优化,核心内涵在于人力资本累积和全要素生产率对经济产出的贡献。新质生产力和绿色生产力都以人与自然和谐共生的生产力观为根基,“新质生产力本身就是绿色生产力”,既指明了“绿色”是新质生产力的必要条件,同时又强调了新质生产力应当促进绿色发展。新质生产力有助于促进经济绿色化和绿色经济化的进一步转变,是绿色发展的驱动力。同时,绿色新质生产力驱动绿色产业与生态产品第四产业蓬勃发展,应成为新的经济增长点。
