文旅融合背景下图书馆服务变革与空间再造研究

新时代环境下,为了充分满足公众对文化生活的多样化需求,公共图书馆应在构建空间服务方面进行开拓与创新。新型阅读空间是近年来公共图书馆领域重点关注的话题之一,空间服务的优化对于全民阅读活动的推广具有不可估量的意义,是实现其社会价值的关键所在。为此,公共图书馆应充分发挥其独特的塑造功能和能动作用,采用多元化的策略来优化空间再造,从而确保图书馆能够持续、健康地运转。基于此,本文以南丹县图书馆为例,重点探讨文旅融合背景下优化图书馆空间服务变革的意义及图书馆空间再造的驱动力,并以此为依据提出优化图书馆服务变革与空间再造的策略,以供参考。

广西生态系统服务价值空间分布与生态保护对策

以广西90个县(市)为研究区,采用2005年广西土地利用变更数据,对照我国陆地生态系统单位面积服务价值表,测算广西各县(市)的生态系统服务价值。结果表明,广西生态系统服务价值可归纳为生态系统服务价值高的区域、生态系统服务价值中等的区域、生态系统服务价值低的区域三大类,其中,生态系统服务价值高的县(市)主要分布在桂西北山区、桂东山区、桂东南丘陵区、桂北山区、桂东北山区;生态系统服务价值中等的县(市)主要分布在桂南丘陵台地区和桂西南山地区;生态系统服务价值低的县(市)主要分布在桂中盆地、桂西岩溶山区和桂西北岩溶山区。

Urban spatial expansion and its impact on ecological service values of Chongqing City Proper in the last 30 years

Based on the remote sensing images of urban land use of Chongqing City Proper in the last 30years(from 1978 to 2011),The paper focuses on the impact of urban spatial expansion on urban ecosystem service.The charactereristics of urban spatial expansion pattern are expressed by Landscape Expansion Index and Index of Fractal Dimension.Taking advantage of calculation of these two indices,changes of the ecological service values in the main urban area of Chongqing caused by the variation of urban expansion patterns are evaluated and the interrelationship is analyzed.The main conclusions and results are as follows;in Chongqing City Proper,the ecological service value decreased rapidly from 1978 to 2011,especially in the period of 2002-2011.Urban spatial expansion pattern has exerted significant impact on urban ecosystem service value.Edge-expansion pattern broke into a great deal of urban enclaves and caused the disadvantage effect of the function of urban ecological system.At the same time,negative correlation existed between the indices of fractal dimension and the ecosystem service value.

Remote Sensing of Ecosystem Services:An Opportunity for Spatially Explicit Assessment

Ecosystem service is an emerging concept that grows to be a hot research area in ecology.Spatially explicit ecosystem service values are important for ecosystem service management.However,it is difficult to quantify ecosystem services.Remote sensing provides images covering Earth surface,which by nature are spatially explicit.Thus,remote sensing can be useful for quantitative assessment of ecosystem services.This paper reviews spatially explicit ecosystem service studies conducted in ecology and remote sensing in order to find out how remote sensing can be used for ecosystem service assessment.Several important areas considered include land cover,biodiversity,and carbon,water and soil related ecosystem services.We found that remote sensing can be used for ecosystem service assessment in three different ways:direct monitoring,indirect monitoring,and combined use with ecosystem models.Some plant and water related ecosystem services can be directly monitored by remote sensing.Most commonly,remote sensing can provide surrogate information on plant and soil characteristics in an ecosystem.For ecosystem process related ecosystem services,remote sensing can help measure spatially explicit parameters.We conclude that acquiring good in-situ measurements and selecting appropriate remote sensor data in terms of resolution are critical for accurate assessment of ecosystem services.

A Review on the Supply-Demand Relationship and Spatial Flows of Ecosystem Services

Research on spatial flow as it relates to the relationship between the supply and demand of ecosystem services supports a significant connection between the supply of ecosystem services and human well-being.Understanding the entire process of the production and flow,as well as the use of ecosystem services,accurately assessing the balance of supply and demand of ecosystem services,and establishing a two-way feedback relationship between supply and demand are vital for the scientific management of the ecosystem and ensuring the sustainable development of regional resources.Based on a large number of relevant publications,this paper comprehensively summarizes the concepts and assessment methods of ecosystem service supply and demand from the perspective of ecosystem service supply and demand,and discusses the impacts of land use and climate change on the temporal and spatial changes of ecosystem services under the background of global change.Then,an analysis of the research progress in the ecosystem services spatial flow indicated that there are still deficiencies in the quantification of cultural services,the dynamics of ecosystem service flow and the driving mechanism of ecosystem services.We also propose that clarifying the driving mechanism and transfer process of ecosystem services,and realizing the mutual conversion between different spatial-temporal scales of ecosystem services,is an important approach for improving the application of ecosystem services research in practice in the future.
