广西海洋休闲渔业开发研究

在海洋渔业区域减少和资源退化压力下,利用滨海和海洋资源发展海洋休闲渔业,对于促进地方经济发展、增加就业、安置转产转业渔民和调整海洋渔业结构具有重要意义。文章介绍了海洋休闲渔业资源的类型,以及广西海洋休闲渔业的优势,并对广西海洋休闲渔业发展的思路及其模式作了分析和探讨。     

湛江沿海渔民转产转业问题及对策

湛江沿海渔民转产转业的形成原因有:过度的近海捕捞,严重的海洋环境污染,近海的捕捞渔民的经济效益下降和作业渔场面积减少。存在的问题有:需转产转业的渔民数量大,支持转产转业的资金数量有限,渔民综合素质较低,退出捕捞行业的成本高。在此基础上提出了解决沿海捕捞渔民转产转业问题的措施有:政府出台相关的财政政策,积极发展海水养殖业,积极发展滨海旅游业与休闲渔业相结合,调整经济结构,加快工业化的进程。     

对广西滨海旅游开发的思考

广西滨海的3个城市北海、防城港、钦州,有着良好的区位优势和丰富的旅游资源,其中北海银滩被列为国家级旅游度假区。近年来,北海周边及其它两个城市相继开发了不少旅游项目,旅游业发展较快。但与广西其它城市及我国其它滨海地区相比,广西滨海旅游业没有发展到它应有的高度。本文在分析广西滨海旅游市场的优势、现状及成因的基础上,从产品开发和宣传促销两个方面提出了一些新的思路。     

社交媒体影响下城市休闲空间分布新特征:基于小红书打卡地与POI的对比分析

移动信息通信技术与社交媒体对日常生活的嵌入日益加深,影响了居民休闲活动区位选择,但就其影响的空间规律性特征认识相对欠缺。研究基于对比的视角,选取大连市小红书休闲打卡点位数据与同类别休闲POI数据,从集中度与集群度2个维度、在主城区与行政街道两个尺度上,采用核密度估计、热点分析、DBSCAN等空间分析方法测度对比两类休闲空间的分布特征,并据此提出初步的机制解析。研究发现：(1)休闲打卡地大多分布于城市核心区内,但分布范围更小、核心数量更少;(2)在宏观尺度上,休闲打卡地呈现出更低的集中度（差值约3%）与集群度（平均差值约18%）,分布具有明显的“均质化散布”特征,在街道尺度上分布趋势相同,但在不同街道2类指标的差值大小存在显著不同;(3)休闲打卡地的热点集聚区范围更小,就其分布位置而言,在宏观与街道尺度上分别有85%与77%的休闲打卡地热点集聚区位于全量休闲空间热点集聚区内,少量休闲打卡地特有的热点集聚区主要分布于历史街区以及滨海岸线等城市特色风貌区;(4)根据街道内指标高低,休闲打卡地的分布模式可以总结为“原中心集群型”、“原中心散布型”、“新中心散布型”以及“无中心散布型”4类,不同...

北京休闲农业与乡村旅游发展研究

休闲农业与乡村旅游在我国已经有20多年的发展历史。北京作为最早开始发展休闲农业与乡村旅游的城市,具备良好的农业资源条件和旅游发展环境。至2007年底,北京全市实际经营的农业观光园达到1302个,观光园总收入13.1亿元,农业观光园和民俗旅游户接待人数达到2614.4万人次,休闲农业与乡村旅游的发展呈现勃勃生机。目前北京休闲农业与乡村旅游发展主要有农业观光休闲、民俗文化休闲、休闲度假三大类型;地域布局呈现近郊、中郊平原区、远郊山区三大圈层结构;与风景旅游区相结合,形成十大发展基地。"十一五"期间,北京市提出重点打造五条农业精品旅游专线,必将进一步推进观光休闲农业与乡村旅游的健康发展。本文从发展条件、发展现状和特点、发展布局、旅游线路组织等几个方面,对北京市休闲农业与乡村旅游的发展进行了全面、系统的分析和总结,并在此基础上提出了北京市休闲农业与乡村旅游发展对策与建议:合理布局、科学管理、加大投入、强化培训、加强法律保障。

土地整治应注重生态景观服务功能

在城乡一体化发展的要求下,土地整治不能仅限于提高土地综合产能、改善生态环境,还要挖掘乡村景观的美学和文化价值。随着城乡一体化发展,乡村作为城乡发展重要的绿色空间和旅游休闲场所,具有重要的生态服务和景观服务功能。在城乡一体化发展的要求下,土地整治不能仅限于提高土地综合产能、改善生态环境,还要挖掘乡村景观的美学和文化价值。

Thermohaline structure inhomogeneity associated with polynia at the northern margin of Emery Ice-shelf

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area.     

Phylogenetic analysis of cultivable bacteria isolated from Arctic sea-ice

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter.

Relationship of Arctic sea ice and Northern Hemispheric 500 hPa Polar vortices

Using the NCEP/NCAR reanalysis monthly 500 hPa height data on a 2.5 latitude-longitude grid and 1°×1° sea ice data,the polar vortex area,intensity index and arctic sea ice area index are calculated respectively,and the meridional distribution,period variation and the abrupts in the long range trend are analyzed to study their relationship.The results show that the meridional distribution of sea ice and polar vortex h-ave distinctive difference,the relative positions of them are different in the eastern and western hemispheres,and exept they have periods of 4 months,quasi half year,quasi year,4-5 years and 10 years commonly,and each of them has its own respective variation as well.The sea ice area is decreasing apparently since 1980's,so is the polar vortex area,but their abrupt changge time are different totally.The area of sea ice and polar vortex has prominent positive correlation,but the relationship of sea ice intensity,polar vortex intensity,polar vortex area is complicated.
