新疆冰雪旅游资源适宜性评价研究

冰雪旅游正在成为冬季旅游出行的新选择。新疆冰雪旅游资源丰富,如何合理开发利用资源成为当地旅游开发亟待解决的问题,因此本文从旅游资源适宜性角度出发,选取自然条件、旅游资源、社会经济和交通可达性等方面的18个影响因子,采用层次分析法（AHP）和熵值法（EWM）确定组合权重,运用GIS空间分析技术和多因子加权评价模型（MCE）对研究区冰雪旅游资源适宜性进行评价。研究结果显示：① 就自然条件来看,伊犁东部、阿勒泰北部沿山脉边缘的丘陵和平原等地区较适宜发展冰雪旅游;② 阿勒泰地区和乌鲁木齐市的旅游资源相关基础设施完备,昌吉和伊犁在旅游资源方面也有较强竞争力;③ 社会经济来看,伊犁、乌鲁木齐市和阿勒泰地区为代表的北疆城市较南疆有更强的游客接待能力;④ 伊犁、乌昌经济带沿线地区交通可达性明显优于南疆各地州市。新疆冰雪旅游综合适宜性指数为1.8622-7.5724之间,其中天山北坡、阿勒泰北部、伊犁、塔城北部、哈密中部等地区为高度适宜;南疆大部分区域处于中低度适宜。建议通过加强新型旅游资源开发和整合,积极承办大型冰雪运动相关赛事,借助丝绸之路经济带发展交通道路建设,以加速推进新疆冰雪旅游发展。本研究可为冰雪旅游区开发和选址提供空间导向和科学依据。

Quantitative evaluation and regionalization of tourism resources in Guangxi

Since the 1970s foreign and Chinese scholars have researched into quantitative evaluation of tourism resources by mathematical method early or late and made great progress. Guangxi is in the south of China and rich in tourism resources with picturesque scenery. In this paper, Guangxi’s tourism resources are quantitatively evaluated by method of analytic hierarchy process. Firstly a modular tree of quantitative evaluation for tourism resources of Guangxi is set up and weighted values of evaluative factors are defined by method of consulting experts. On the basis of a great amount of data from investigation, synthetic evaluation indexes and their order of tourism resources of 22 cities and counties in Guangxi are calculated. Then, the tourism resources of Grangxi are divided into 6 regions and their development orientations are described by a combination of quantitative analysis and qualitative analysis. The study would be helpful to the exploitation of tourism resource of Guangxi.     

综合物探在高层建筑选址工作中的应用

基于地下水流系统理论的岩溶隧道涌突水来源及路径分析

双龙洞是国家重点风景名胜区，拟建金华山隧道位于浙江省金华市双龙洞景区北东向约12 km处，金华山隧道的开挖将可能导致双龙洞景区岩溶水的疏干，同时隧道也可能遭受岩溶涌突水的安全隐患。基于地下水流系统理论，结合研究区水文地质条件调查成果，岩溶地下水流系统的划分，隧道出口段关键岩溶分布区地质结构的分析，以及水文地球化学测试分析结果，对双龙洞与隧址区之间各岩溶地下水流系统间的水力联系及涌突水可能性进行了分析。结果表明，隧道出口段开挖若揭露至其所处岩溶含水层并进行排水，影响的只是周边有限的岩溶水及裂隙水，不会直接连通研究区西侧大规模岩溶地下水流系统；隧道施工和运行期间对双龙洞景区的岩溶水基本不会产生影响，同时双龙洞岩溶水也不会对隧道出口段形成直接的涌突水威胁。在岩溶区隧道涌突水来源的研究中，基于地下水流系统理论合理划分岩溶地下水流系统并分析各系统间水力联系，是分析涌突水来源及防范涌突水灾害的必要前提。      

典型贫困山区旅游景点可达性评价方法研究

旅游景点的可达性水平不仅可以反映游客到达的方便程度,也用来衡量区域旅游业发展的潜力,而对于贫困山区旅游景点的可达性研究还可为旅游扶贫的开展工作提供理论参考。本文聚焦典型贫困山区,探究交通成本及复杂地形特征对旅游景点可达性的影响。首先,文章通过连接度指数和通达度指数的相关分析,了解研究区旅游网络的整体连通状况;然后,运用累积耗费距离法,分别基于不同等级交通因素和坡度、海拔等地形因素,对研究区旅游景点可达性和县级行政单元整体可达性进行对比分析,并提出了一种综合考虑交通因素和地形因素的可达性评价方法。研究表明：交通因素分析法弱化了水域对于可达性的阻隔作用;地形因素分析法忽视了交通条件对于可达性的影响;而综合考虑不同等级交通因素和复杂地形因素的可达性评价方法,既可有效识别水域对于贫困山区旅游景点可达性的阻隔作用,也体现了交通条件的改善对于自然环境下可达性水平的提升作用。

REGIONAL TOURISM COOPERATION IN TRIANGLE ZONE OF LIAONING PROVINCE

Strengthening the regional tourism cooperation is the requirement of both tourism development and tourist competition drive. On the one hand, resources, products, market and infrastructure in tourism are characteristics of half-public goods, which are the externalities. On the other hand, tourism competition has evolved from individual scenic spot, or finn competition to regional competition, which also requires urgent regional tourism cooperation. In recent years, the regional economic cooperation has been becoming popular in the world. The triangle tourism zone of Liaoning Province, constituted by Shenyang, Dalian and Dandong, is the core region of Liaoning tourism system. This regional tourism cooperation has been raised for a long time, but has not made substantial progress as yet. In recent years, the strategic cooperation among them has been becoming urgent, along with the change of tourism competition models, as well as the desire for building a Northeast Asia tourist economy circle. Based on literature, this paper establishes a conceptual frame of regional tourism cooperation and applies it in the analysis of the strategic tourism cooperation of Liaoning Province＇s golden triangle zone. This paper firstly examines both qualifications and motives concerning with cooperation among the three cities, and believes that the biggest difficulties involve traditional ideas, administrative institutions, communications, economic performances, time constraints, and more overlap among their tourist markets. Then this paper continues to construct a cooperating mechanism, including participant arrangements, construction of operating mechanism and construction of assisting mechanism. At last, this paper proposes approaches to the strategic cooperation such as introducing Xiuyan County, strategic integration and developing differentiated and complemented tourism products.

Integrating multisource RS data and GIS techniques to assist the evaluation of resource-environment carrying capacity in karst mountainous area

The karst mountainous area is an ecologically fragile region with prominent humanland contradictions. The resource-environment carrying capacity(RECC) of this region needs to be further clarified. The development of remote sensing(RS) and geographic information system(GIS) provides data sources and processing platform for RECC monitoring. This study analyzed and established the evaluation index system of RECC by considering particularity in the karst mountainous area of Southwest China; processed multisource RS data(Sentinel-2, Aster-DEM and Landsat-8) to extract the spatial distributions of nine key indexes by GIS techniques(information classification, overlay analysis and raster calculation); proposed the methods of index integration and fuzzy comprehensive evaluation of the RECC by GIS; and took a typical area, Guangnan County in Yunnan Province of China, as an experimental area to explore the effectiveness of the indexes and methods. The results showed that:(1) The important indexes affecting the RECC of karst mountainous area are water resources, tourism resources, position resources, geographical environment and soil erosion environment.(2) Data on cultivated land, construction land, minerals, transportation, water conservancy, ecosystem services, topography, soil erosion and rocky desertification can be obtained from RS data. GIS techniques integrate the information into the RECC results. The data extraction and processing methods are feasible on evaluating RECC.(3) The RECC of Guangnan County was in the mid-carrying level in 2018. The midcarrying and low-carrying levels were the main types, accounting for more than 80.00% of the total study area. The areas with high carrying capacity were mainly distributed in the northern regions of the northwest-southeast line of the county, and other areas have a low carrying capacity comparatively. The coordination between regional resource-environment status and socioeconomic development is the key to improve RECC. This study explores the evaluation index system of RECC in karst mountainous area and the application of multisource RS data and GIS techniques in the comprehensive evaluation. The methods can be applied in related fields to provide suggestions for data/information extraction and integration, and sustainable development.

THE EVALUATION AND ANALYSIS OF THE TOURISM RESOURCES IN JILIN PROVINCE

This paper comprehensively evaluates and analyzes the tourism resources in Jilin Province,China.And it consists of three parts.The first two parts are on the resources evaluation and analysis.Based on the results of evaluation about the structural and spatial distribution of the tourism resources,it is found that ,the natural resources play fundamen-tal roles in Jilin,while the human and cultural resources are important complementary parts as well .In the spatial distribu-tion analysis,the resources show the characteristic of “six clusters“and “three belts “spatial relations.Four clusters are centered on the cities,which are Changchum,Jilin,Baicheng,Tonghua and Jiˊan;one cluster is around the Changbai Moutains and one cluster nears the frontier at Tumen between China,Russia and P.D.R.Korea.And the three belts are;1)The west belt.It contains Xianghai and Momoge natural protection region.The evident of this zone is its ecologi-cal and ethical tourism resources.2)The middle belt characterized by urban traveling and recreation,including Jilin and Changchum,together with their nearby Nongˊan and Siping.3)The last belt is also the most important one,which is the east zone.It covers the Changbai Mountains,the golden triangles of Tonghua and the Tumen River.This zone is remark-able for its abundant natural landscapes and unique folk-customs.In the last part the concept planning is briefly construct-ed for the tourism resources in Jilin Province according to the above evaluation and analysis.
