Ecological function transitions of land use in the Beibu Gulf Economic Zone from the perspective of production-living-ecological space

The ecological function of land use is the basis for developing an ecological civilization and realizing sustainable development.This paper may help guide the coordination of economic development and ecological development in China’s coastal border areas.Based on theoretical analysis,this paper studies the spatiotemporal evolution of the functional spaces and the ecological function transitions of land use in the Beibu Gulf Economic Zone(BGEZ)by analyzing patterns,processes,and factors by applying eco-environmental quality index,grid subdivision,kriging interpolation,barycenter model,and Geodetector.This paper constructs a theoretical framework of ecological function transitions of land use based on the research idea of“system-pattern-process-factor”,and carries out empirical research.Some conclusions can be drawn as follows:(1)The ecological space in the BGEZ has continuously decreased,converting mainly into agricultural production space and industrial-mining production space.The production space has expanded slowly.The area of living space in the BGEZ has increased rapidly.(2)The ecological function of land use in the BGEZ has continued to weaken,especially in the southern part of the BGEZ.The“high-sub-high”quality zones of ecological function are retreating to the north.(3)There were more deterioration transition areas than optimization transition areas of ecological function in the BGEZ.The former were mostly located in the central and southern urbanized areas of the BGEZ,whereas the latter were mostly located in the edge zones of district and county units.(4)As for the driving factors of the deterioration transitions of land use ecological function in the BGEZ,the significant trend of“de-ecologization”of the land cover/land use structure was the dominant driving factor;the interactions among the“natural-socioeconomic-managerial”systems were the main recessive factor.The natural system played a fundamental role,and the driving force of natural factors was the strongest.The industrialization,urbanization,and GDP increment in the socioeconomic system and the policy positioning of development intensity in the managerial system played a significant role.The interactions among natural factors,road construction,and industrial non-agricultural transformation had a“fuze”effect on stimulating driving forces.

建筑美术教育的回顾与前瞻

长期以来,在我国的高等建筑院校当中,艺术课的发展与重视程度是有一定的局限,再一次探索美术教育在所属建筑专业基础课中的地位,探寻其作用的不足因素,则有利于建筑教学观念的转变以及各门课之间的相互协调与发展。

高校教师住宅区建设的教育学考察

高校教师住宅区孕含着丰富的教育蕴意,既具有充分利用高校各类资源、扩大师生交流的时间和空间、稳定青年教师队伍等显性功能,又具有提升校园文化品位、为教师子女的成长提供良好的人文环境等隐性功能。高校要有前瞻性的眼光和“以人为本”的办学理念,以社会效益为己任,采取切实措施建设自己的教师住宅区。

中国歌曲在对外汉语教学中的双重功能

针对留学生在汉语学习时会产生母语负迁移这一问题,依据人的音乐性、音乐与语言的同宗同源等理论,在教学中尝试采用教唱中国歌曲的教学方法。理论研究和教学实践表明:中国歌曲在对外汉语教学中具有隐形、显性的双重功能。在对外汉语教学中引入中国歌曲,既有助于培养汉语习得者的语音、语调和语感,又能够加深留学生对中国文化的认同感。

高校图书馆的教育职能及其开发探析

高校图书馆具有显性职能和隐性职能,隐性职能即通过显性职能所要实现的目标——教育职能。探讨了高校图书馆教育职能的具体内容,并提出高校图书馆开发教育职能的途径和方法。

内P-显性信息规律显性-隐性特征与显性信息规律发现

函数P-集合(function packet sets)是把函数概念引入到P-集合内(packet sets),改进P-集合得到的,函数P-集合具有动态特性,规律(函数)特性。函数P-集合是由函数内P-集合SF(function internal packet set SF)与函数外P-集合SF(function outer packet set SF)构成的函数集合对;或者,(SF,SF)是函数P-集合.利用函数内P-集合与生物遗传学中的"显性","隐性"概念交叉,渗透,给出内P-显性信息规律的显性-隐性特征,给出内P-显性信息规律的显性-隐性定理,给出内P-显性信息规律发现准则;利用这些结果,给出内P-显性信息规律发现的应用.

科举文化控制社会分层功能刍议

科举自公元605年创立以来,就以其多元一统性影响和控制了1300余年中国历史的发展和走向。这种控制本身不仅有显性的方式,更多的则是隐性的控制。从科举文化的视角分析它对社会分层的非显性控制,一方面是为了对科举学、考试社会学、考试文化学等学科进行探索;另一方面,则是为了更好地为当代大规模考试的改革及其价值定位提供理论参考。
