陕西翠华山水湫池山崩遗迹形成年代

利用C14测年方法对陕西翠华山不同时期的山崩进行了绝对年龄的初步研究。C14测年数据与宏观野外地质地貌调查的结论吻合,证实了翠华山山崩景观形成为多期性的结论,同时与地震事件有一定的关系,为研究山崩成因提供了科学论据。     

基于地质科学含义的国家地质公园游客认知行为研究——以陕西翠华山国家地质公园为例

以游客对"国家地质公园地质科学含义"的认知水平为研究内容,对陕西翠华山国家地质公园内游客进行了问卷调查,研究结果显示:游客对国家地质公园"地质科学含义"认知程度较低;女性对国家地质公园"地质科学含义"认知程度高于男性;学历越高对"地质科学含义"的认知程度越高;14岁以下和45～64岁之间的游客对地质公园"地质科学含义"呈高认知度;翠华山国家地质公园突出山崩地质遗迹特色赢得了游客对公园特色相对较高的认知评价.在研究分析的基础上提出了以"地质科学含义"为市场认可标准的浅认知度国家地质公园的概念,并对其类型和特征进行了阐述.     

基于地质遗迹保护利用的国家地质公园协调性运作--以翠华山山崩景观国家地质公园为例

根据我国国家地质公园建设中出现的若干问题，结合翠华山国家地质公园的运作实践，提出国家地质公园的主要任务是在保护好地质遗迹资源的前提下，发挥地质遗迹资源的多种功能，坚持“保护与利用相结合，保护第一，利用第二，在保护中利用，以利用促保护”的地质公园建设原则；分析了保护与利用、主景与配景、科普宣传中的科学性与通俗性、地质遗迹景观与生态环境等需要协调的七大问题，分别提出了切实可行的协调措施。     

湖南津市黄牯山第四纪泥砾混杂堆积成因探讨

湖南省津市黄牯山发育一套泥砾混杂堆积,前人曾认为属冰川成因。近年笔者对该套堆积的沉积层序、结构组成、横向变化、砾石组构与表面特征等作了详细考察,发现堆积中下细上粗的层序特征,砾石扁平面的优选定向,沿层理经差异风化和磨蚀所形成的假"冰川擦痕",由壳状裂口经磨蚀、圆化所形成的凹面石,沉积体短距离内的相变,以及周边仅有低矮丘陵的地貌背景等,表明泥砾混杂堆积为泥石流产物,而不是冰川成因。     

新疆阿勒泰市城市山地灾害及减灾对策研究

新疆阿勒泰市坐落于阿尔泰山南麓低山丘陵带的狭长断陷谷地内,相应的生物气候带属干旱荒漠与干草原带,是山地环境变化和人类活动反应最为敏感地带。随着山区资源开发,城镇建设的蓬勃发展,城镇面积不断扩大,周围山区生态环境遭到不同程度的破坏。近30年来,阿勒泰市周边的山洪、水土流失、泥石流、崩塌等山地灾害日趋严重,给当地经济发展和人民生命财产带来了巨大损失,山地灾害成为制约阿勒泰市社会、经济、环境协调持续发展的屏障。在分析山地灾害类型和形成条件基础上,对山地灾害分布规律、活动与危害特征进行了论述,山地灾害对市区造成的直接和间接经济损失及影响进行了综合评估,提出了相应的防灾减灾措施。     

Study on Mountain City Landscape Gradient Characteristics and Urban Construction Coupling: Taking the Yangtze River to the Eastern Ridge Line of Nan Mountain in Chongqing as an Example

China has a vast area of mountains that are of great research interest. Chongqing is a typical mountain city in China. In urban construction, a mountain is not only an important limiting condition for urban development, but also an important condition for shaping the urban form. The area from the Yangtze River to the eastern ridge line of Nan Mountain in Nanan District is strongly representative of mountain cities with a complex landform, fragile ecological environment and a long history and culture. In recent years, the construction and optimization of this area are increasingly closely related to the landscape environment. However, due to the special environments of mountain cities, altitude and landform conditions become the key influencing conditions for further development of the cities. Therefore, this paper takes this region as an example, focuses on remote sensing and field measurement data, combines government data with that from scholarly research, and conducts relevant exploration through GIS, ENVI and some chart processing software. At first, from the perspective of the landscape gradient and urban construction, the characteristics of the urban landscape gradient are sorted out, and the developmental status of each urban area is analyzed. Then, the coupling relationships between the landscape features of each gradient and each urban area are analyzed. Finally, based on the analysis results, three major optimization measures are proposed to maintain ecological harmony in the mountainous area, reconstruct the mountain characteristic culture, and create unique mountain aesthetics, all with the hope of providing some guidance for the future development of the study area and similar mountain cities.
