川东南长宁地区地震活动及b值演化特征

利用全国统一目录和流动台站目录,研究了四川盆地东南部长宁地区的地震活动特征和b值的空间分布特征.研究结果显示,长宁地区的地震活动在时间上呈现明显的分段特征,地震活动在2015年后明显增强;在空间上,长宁地区的地震活动主要集中在以28.3°N为界限的南、北2个地区,对于这2个区域的b值演化,计算结果显示出不同的分段特征....     

兴文侵蚀型天坑的形成演化过程研究

According to the first-hand investigation and study on Xingwen Global Geopark,the results and the data show that apart from Dayanwan and Xiaoyanwan collapsed karst Tiankeng,there are other karst landforms in Bowang Mount scenic spot such as Feiwu Cave,Dao Cave,Cangshuiyan Gorge,Nanxing TanKeng and so on.These typical karst landforms could be regarded as different vestiges of erosive karst Tiankeng of Xingwen Global Geopark,which stand for the evolutional processes of erosive karst Tiankeng separately.Moreover,the evolutional processes of erosive karst Tiankeng could be divided into the following continuous processes:an erosive karst Tiankeng develops from the processes of eroding and dissolving & extending of silo Sinkhole,and subsequently degrades to a large gorge or doline.It is worth pointing out that except for erosion of flowing water,at the same time,collapse effect has been playing extremely important role in the forming processes of these special erosive landforms.     

Research on Fossil Heritages Protection in Xingwen World Geopark

There are various Permian fossil heritages in Xingwen World Geopark.However,during constructing Geopark in recent years,the fossil heritages have suffered more serious damages,and thus the protection models of the fossil heritage are worth studying.This paper describes the fossil heritages’ types,abundance and preservation of the current status quo in the geopark.It turns out that natural factors and human factors are the main reasons why lead to the destruction of fossil heritages.At last,it puts forward the corresponding measures in order to protect the integrity of fossil heritages in the world geopark.     

兴文石海世界地质公园SWOT分析和产品营销战略

兴文世界地质公园拥有全国及世界重要意义的"地球特大漏斗"、"中国最大的石海"和"中国最长的游览洞穴"等景观。采用SWOT分析法,对兴文石海世界地质公园的内部优势、劣势和外部机遇、挑战进行分析,提出了适宜的旅游产品营销战略,以改进其旅游产品和客源市场的开发。     

四川兴文5.7级地震烈度评定及结构震害简析

四川兴文5.7级地震共致宜宾市兴文县、珙县和长宁县3个县22个乡镇受灾,震区抗震设防烈度为Ⅵ度。震区主要建筑物结构类型为框架结构、砖混结构、砖木结构和土木结构,大多数房屋没有经过抗震设防加固,抗震性能一般。通过对震区3个县68个抽样点的调查,发现框架结构和设防砖混结构在此次地震中表现出了良好的抗震性能。同时对不同结构类型房屋的构造方式、分布情况和震害特点进行了分析,并针对不同的震害特征,为今后该地区的灾后恢复重建和防震减灾工作提出了对策建议。     

The Analysis of CO_2 Influence Factors in Tianquan Cave of Xingwen World Geopark

A Vaisala CARBOCAP Hand-Held Carbon Dioxide Meter GM70 was used to measure CO 2 concentration in Tianquan cave of Xingwen world Geopark.The study was done in Tianquan cave during July and August,2008.Data sources include the influence factors of distribution of CO 2:elevation,tourists,cross section and depth of the cave.Results indicated tourists have strong impacts on the CO 2 concentration,while no significant differences could be found among different elevation.Furthermore,significant correlation could be found among the depth of cave,the small cross section,the tourist’s construction and the CO 2 concentration.Those results indicate that the CO 2 concentration in Tianquan cave has no threat to the health of tourists.The results and the data provide a scientific basis for the protection of people’s health and the exploitation of cave tourism.     

兴文岩溶区地质灾害的危害与防治

兴文岩溶区位于兴文县中南部地区,该区拥有丰富的地质旅游资源,在带动地方经济发展上起着不可替代的作用。但复杂的地质背景使得该区的地质灾害呈现出多样性,这不仅会对该区的旅游资源造成不可恢复的损失,而且还会给当地人民的生命财产带来巨大的损失,在一定程度上制约了社会和区域经济的发展。因此,对兴文岩溶区地质灾害的危害进行研究具有十分重要的意义。在分析了该区地质灾害分布和特点的基础上,研究了该区地质灾害的影响因素,并针对其危害提出了可行的防治对策,为兴文地质灾害的防治规划提供参考。     

Fractal on Particle Movement in Storm Steady Current Field of the Permian in Xingwen World Geopark

The particle is not the continuous but fractal medium.It has a diverse scale from several to angstroms.Through different density function of the particle system,mutual influences among factors can be get;especially in the micro aspect,fractal dimension of particle radius distribution influences the system and has a significance to denote the fluidity of the particle.The influences among the particle size,spatial coordinates,density(or concentration) and time are analyzed theoretically and numerically.According to first-grade reaction diffusion model of fractal medium DLK model,the movement of the Brown particle and thermodynamics theory of mechanics can be popularized to the storm current field and gets Γ(t)-D model.

旅游作为兴文县的重点发展支柱产业,对兴文县的经济具有及其重要的作用。通过对兴文县旅游资源、旅游行为、旅游市场及服务设施结构的分析研究,找出制约兴文旅游发展的主导因素,提出了旅游发展改善措施,为兴文旅游业今后健康持续发展提供依据。     

世界地质公园旅游地生命周期影响因素及演变机制——以兴文石海为例

通过使用Butler旅游地生命周期理论,以兴文石海世界地质公园开发最早园区一石海洞乡为研究对象,对景区进行旅游地生命周期划分。同时结合问卷调查数据分析影响该旅游地生命周期演变的主、次因素,以及两者在各阶段的具体演化对旅游地发展的作用,阐明景区主导因素演变机制。研究认为石海洞乡经历了探索期、参与期,现阶段处于发展期,其主导因素分别为：探索期为当地群众,参与期为上级政府、高层官员与专家学者,发展期为当地政府与投资企业。
