Path of Rural Vitalization Based on Coupling Perspective of Township Construction and Resource Environment in Jiangsu Province,China

Recently,the field of rural vitalization has received extensive research attention.However,only few studies have proposed an approach to rural vitalization from the coupling perspective of township construction and the resource environment.Taking Jiangsu Province of China as the study area,we constructed index systems of township construction function types and resource environments.Based on 875 township study units in Jiangsu,we characterized the township construction function type and resource environment and analyzed the dynamic process of their coupling from 2005 to 2017.The results are as follows:1)the townships of planting and breeding types in Jiangsu were mainly distributed in northern and central Jiangsu;the townships of business travel,industry,and integrated types were mainly distributed in southern Jiangsu;and the townships of ecological type were irregularly distributed throughout Jiangsu.2)Resource environment factors and township construction function types in Jiangsu clustered based on their location with some overlap.3)Spatial variability in the degree of coupling level between township construction and the resource environment in Jiangsu was not apparent,and low coupling levels accounted for most of the study units.The sum of the number of medium and high coupling townships in southern,central,and northern Jiangsu was roughly equal,and the coupling level between township construction and the resource environment in southern Jiangsu evolved remained unchanged,whereas that in the central and northern Jiangsu became imbalanced.4)In Jiangsu,township construction was mainly constrained by water resources,and the constraint parameters gradually increase.Large variability in resource environment constraint was observed in northern,central,and southern Jiangsu for different township construction function types.Based on these findings,we proposed the implementation of targeted rural vitalization strategies.

A New Type Anticorrosion Coating for Ocean Reinforced Concrete Structures

Corrosion of reinforced concrete structures is a serious problem in ocean engineering. As an orientation of study, anticorrosion coating technique is developed and widely applied, but many problems need to be solved. LSW-2 type anticorrosion coating for maritime reinforced concrete structures is characterized by sea water resistance, salt fog resistance, moisture and heal resistance as well as impermeability to chlorions. The new type coating can be applied to wet concrete surface by conventional construction technique. It is a breakthrough in solving the above mentioned problem. The paper mainly introduces the test results, the property indices, coating procedure, construction technique and economic benefit of Ihe coating.

“不A不B”格式的表义类型与构式化等级

文章认为,宏观上,认为决定"不A不B"格式不同用法的关键是变量A与B之间的意义关系,表示全量范围的并列式是其基本类型,A与B之间是同类非同义词语;当A、B间的语义关系突破这个范围时,就变成偏正式;当A、B之间是同义词语,就变成复指式;当A、B之间是反义关系,就变成对立式,后者又因感情色彩的不同分为适中类、不适类。微观上,同类"不A不B"格式在不同语境中用法的不同源于构式化程度不同,构式化程度高的"不A不B"格式特征为主观化、隐喻化、消极表义化。

构式“V来V去”的来源、承继及类型学意义

构式“V来V去”的反复义和交互义有着各自不同的演化路径、动因和机制。“V来V去”的反复义是构式化的结果,是语法化而逐步显现的构式义。它的交互义是构式语法化的结果,是基于反复体“V来V去”的构式义基础上的语用承继义,是一种在语境中呈现出来的意义。汉语“V来V去”的构式化路径有着一定的类型学意义。

属性凸显义构式“N就是N”的功用与成因

文章讨论了构式“N就是N”与其同形异质一般结构的区别特征、构式语义及其形成所需的语境条件、语境表现构式语义时背后的认知理据性、话语功能和构式化历程及其动因。区别特征上,构式的常项构件凝固度高于一般结构,变项构件前N的准入范围小于一般结构,后N不受回指而一般结构可以,构式不可搭配语气词“呗”而一般结构可以。构式语义上,构式表凸显名词后N的社会属性义,并主要受两种语境条件的制约。话语功能上,利用关联理论讨论了构式后N所凸显的属性是认知最佳关联性的体现,且构式可表认同性评述、语力强化和合理感叹等功能。构式化上,“N就是N”在言者追求高价值信息、隐含比较对象与特定语境促动等动因的联合作用下完成构式化。
