Assessment of the natural-cultural resources in Çanakkale for nature-based tourism

While the world is going into different tourism expectations, the tourism understanding in Turkey is defined as tourism in the sea-sand-sun triangle. However, it is possible to contribute to the income and local development of the indigenous people by developing nature-based tourism. Besides, with the sustainable use and preservation of the natural-cultural assets, the damage of the traditional tourism industry on the natural and cultural environment could be reduced. In this study, it is aimed to bring up the nature-based tourism concept in Çanakkale by evaluating the nature-based tourism industry in the general of Turkey and assessing the natural-cultural resources that Çanakkale comprehends. The most important areas that have a nature-based tourism potential in Çanakkale and the tourism activities that are most suitable for these areas have been determined.     

Coincidence and Upgrade： A Typical Case Study of Rural Ecotourism Development

At present, internal rural tourism is at the stage of upgrading and renewing, and ecotourism has been considered to be the main direction. This paper discussed the concepts and criteria of rural tourism and ecotourism, analyzed a typical case of Nongke Village of Chengdu City-being considered to be the first rural tourism site in China, went deep into the problems of the contents and criteria of the development of rural ecotourism, and tried to probe into the principles of the development of rural ecotourism both theoretically and practically so as to understand the rules of the development of rural ecotourism .     

Ecological and genetic characteristics of the distribution of <Emphasis Type="Italic">Bradybaena fruticum</Emphasis> Mull. (mollusca,gastropoda, pulmonata) in a forest-steppe landscape

The distribution pattern of the gastropod Bradybaena fruticum has been studied in a forest-steppe landscape. Analysis of the frequencies of polymorphic biochemical and conchological characters has yielded preliminary results on the characteristics of the species population structure whose formation was determined by a set of natural and anthropogenic factors.Translated from Ekologiya, No. 1, 2005, pp. 39–47.Original Russian Text Copyright © 2005 by Snegin.     

可持续旅游及其区域实现途径探讨—以井冈山风景名胜区为例

可持续旅游是 80年代中期以后提出的关于旅游业发展的新思想。经过十多年的不断拓展深化 ,已经得到世界各国的广泛认同 ,并作为跨世纪旅游业发展的战略指导思想。本文从可持续旅游的由来和对可持续旅游内涵实质的界定角度出发 ,结合可持续旅游实现途径的探讨 ,以井冈山风景名胜区为例 ,对风景区旅游业可持续发展进行了深入的探讨 ,为景区的发展规划提出了战略性构想 ,以期能对井冈山风景名胜区旅游资源的可持续利用和旅游业的可持续发展起到抛砖引玉的作用     

旅游地的类生命特征研究

把旅游地视为一个特殊生命体和特殊的生态系统．旅游地与生物体存在非常类似的机理。具有旅游地生命周期、旅游地生态系统、旅游地之间存在诸如共生、竞争、寄生、捕食生态空间关系等明显的类生命特征。研究旅游地的类生命特征．为运用生态学理论研究旅游发展问题提供了可靠依据和切实可行性，为更好地解释和透视旅游发展问题实质提供了崭新的途径与思路，生态学理论在旅游中的应用和解决旅游问题具有现实的可能性和潜在的应用价值，在丰富旅游学与生态学理论的同时，指导并促进旅游业的可持续发展。     

The Influence of Linear Elements on Plant Species Diversity of Mediterranean Rural Landscapes: Assessment of Different Indices and Statistical Approaches

This paper mainly aims to study the linear element influence on the estimation of vascular plant species diversity in five Mediterranean landscapes modeled as land cover patch mosaics. These landscapes have several core habitats and a different set of linear elements -habitat edges or ecotones, roads or railways, rivers, streams and hedgerows on farm land- whose plant composition were examined. Secondly, it aims to check plant diversity estimation in Mediterranean landscapes using parametric and non-parametric procedures, with two indices: Species richness and Shannon index.Land cover types and landscape linear elements were identified from aerial photographs. Their spatial information was processed using GIS techniques. Field plots were selected using a stratified sampling design according to relieve and tree density of each habitat type. A 50×20 m² multi-scale sampling plot was designed for the core habitats and across the main landscape linear elements. Richness and diversity of plant species were estimated by comparing the observed field data to ICE (Incidence-based Coverage Estimator) and ACE (Abundance-based Coverage Estimator) non-parametric estimators.The species density, percentage of unique species, and alpha diversity per plot were significantly higher (p < 0.05) in linear elements than in core habitats. ICE estimate of number of species was 32% higher than of ACE estimate, which did not differ significantly from the observed values. Accumulated species richness in core habitats together with linear elements, were significantly higher than those recorded only in the core habitats in all the landscapes. Conversely, Shannon diversity index did not show significant differences.     

草原旅游发展中旅游管理部门环境意识的调查研究

根据环境意识结构．设计了旅游管理部门环境意识调查问卷。其主要的指标体系包括：旅游环境知识水平、旅游环境态度、旅游环境评价和旅游环境行为四个方面。对指标体系各部分之间以及每一指标部分的每一题目之间的相对重要性进行权重的确定．而且对各部分的每道题目的各个选项予以赋分。基于权重和赋分．结合调查问卷的实际情况，设计了指标体系各部分评价模型和环境意识总体评价模型。以此来计算草原旅游发展中旅游管理部门环境意识水平的综合得分。经过分析得知，旅游管理部门环境意识模式是“环境知识制约型”模式。     

不同空间划分方式下袁河流域景观结构对水质的影响

近年来景观结构的水文效应受到关注,研究不同空间划分方式下景观结构对河流营养盐、重金属变化的影响机制对于流域生态保护具有重要意义.本文于2018年7月和2019年1月在袁河干流及支流38个采样点采集水样,测定水体营养盐类污染指标（DO、NO₃^--N、NH₄⁺-N、TP和DOC浓度）和重金属类污染指标（Cr、Mn、Fe、Cu、Zn、As、Cd和Pb浓度）.基于前向变量选择、冗余分析等方法,筛选景观结构指标,量化其在不同尺度下对水体营养盐、重金属变化的影响.结果表明：①农田、斑块密度（PD）、斑块聚集指数（COHESION）及散布与并列指数（IJI）是影响水体营养盐变化的主要指标.林地、建设用地（Res）、平均最近邻体距离（ENN_MN）和最大斑块指数（LPI）的组合是影响重金属变化的主要指标.②在河岸缓冲带与圆形缓冲区划分方式下,景观结构均在100 m尺度对营养盐变化解释能力最强,平均解释率分别为31.5%、24.3%,均在1000 m尺度对重金属变化解释能力最强,平均解释率分别为32.0%、42.6%.③100 m河岸缓冲带和子流域尺度分别是景观结构影响水体营养盐、重金属变化的最佳空间尺度,平均解释率分别为31.5%、42.8%.以上结果表明,针对水体不同的污染类型,采用对应的划分方式及缓冲尺度有助于提高定量分析精度,为流域水环境保护、景观优化与管理提供科学依据.     

乡村文化记忆资源的“文—旅”协同评价模型与应用——以苏州金庭镇为例

乡村文化记忆资源是乡村“文—旅”协同的链接点。基于文化记忆理论从文化信息层、物质载体层与社会行为层解析其内涵和协同框架,构建“文—旅”空间协调度、文化记忆连续性和旅游市场认同度的协同评价模型,以苏州金庭镇为例进行实证分析。结果表明:（1）时间格局上,旅游景点与生活生产类空间关联性不断提升,与功能象征类空间依赖减弱,与社会表征类和精神意识类空间关系有所降低但维持高度耦合水平。（2）空间格局上,与生活生产类空间呈极核带状格局,与其余三类空间呈现一核多极格局。（3）旅游景点与生活生产类空间协同关系从“文—旅”空间协调度、文化记忆连续性转向旅游市场认同度为主导,其余空间以“文—旅”空间协调度为主导。（4）影响协同关系的机制包括记忆延续与文化交融、空间优化与旅游融合和社会支持与政策保障等。研究结论可为乡村旅游地的文化振兴和文旅融合提供理论指导和应用模式。
