International Journal of Biological Sciences and Applications. Lianas, Vol. 4, No. 1, 2017, pp. 1-6. Resistance Abstract Merremia boisiana (Gagnep.) Ooststr. (Convolvulaceae), a perennial evergreen woody vine in South Asia that is rapidly increasing its abundance and geographical range, has become a pest to forests in Hainan during the last two decades. M. boisiana typically Received: March 19, 2017 invades secondary forests, shrub lands, and open woodlands, but has now expanded to Accepted: March 27, 2017 natural forests in Wuzhi Mountain where there is tourism-associated disturbance. We did Published: June 7, 2017 some survey and transplantation experiment to examine (1) where can seedlings of M. boisiana emerge, and (2) where do emerged seedlings have the potential to grow larger (e.g., reach the forest canopy). Surveys found that mature plants and emerged seedlings of M. boisiana were mainly distributed within 20 m from the tourist path, but a few reached the forest interior by more than 40 m. -

After the first impoundment in June 2003, many landslides occurred or reactivated. Shuping landslide is one of the most active landslides among them. In this paper, the deformation of the Shuping landslide monitored by GPS, extensometers, and crack measurements are summarized. Also, for the investigation of the groundwater situation, 1m-depth ground temperature measurement was conducted, and the groundwater veins were estimated. Based on the monitoring data and exploration results, a deformation model of the landslide caused by impoundment of reservoir was proposed. Keywords: landslide, displacement monitoring, reservoir impoundment, groundwater 1. Introduction River in China is the largest hydro-electricity project in the world.

Failure Mode and Stability of a Landslide under Water Level Fluctuation Miaojun Sun Power China Huadong Engineering Corporation Limited, Hangzhou, PR China e-mail: [email protected] Zhigang Shan Power China Huadong Engineering Corporation Limited, Hangzhou, PR China e-mail: [email protected] Mingyuan Wang Power China Huadong Engineering Corporation Limited, Hangzhou, PR China e-mail:[email protected] Weida Ni Power China Huadong Engineering Corporation Limited, Hangzhou, PR China e-mail:[email protected] ABSTRACT The failure mode and mechanism of a landslide are vital to landslide reinforcement design. The Tanjiawan landslide was used as an example to investigate into the failure mode and mechanism of the landslides in the Three Gorges Dam Reservoir, China. The structure of the landslide was analyzed through a lot of field investigations. Moreover, the failure mode of the landslide was studied with the data obtained by an integrated monitoring system, including GPS monitoring, extensometer and inclinometer monitoring. Finally, the stability of the landslide was evaluated with the rigid-body limit equilibrium method. It can be concluded that the landslide is a pushing landslide containing two main sub-landslides. The deformation of the Tanjiawan landslide develops from back to front relative to the Yangtze River. And the failure of this landslide is caused by the coupled actions of the rainfall and water fluctuation. The inclusions reported in this paper provide some useful suggest for the stability analysis and control structure design of landslides with a similar slope structure in the Three Gorges Reservoir region. KEYWORDS: reservoir landslide; slope structure; failure mode; stability; monitoring system; INTRODUCTION Three Gorges Dam on the Yangtze River is the largest hydro-electricity project in the world[1-4]. -

Comparative Study on the Characteristics of College Students’ Physical Fitness Between Li and Dai College Students in Two Tropic Zones
2017 3rd International Conference on Management Science and Innovative Education (MSIE 2017) ISBN: 978-1-60595-488-2 Comparative Study on the Characteristics of College Students’ Physical Fitness between Li and Dai College Students in Two Tropic Zones YINAN MA, FUSONG HU and YIMEI DUAN ABSTRACT Object: explore the differences of physique characteristics between Dai college students in Xishuangbanna tropic zone and Li college students in Five Finger Mountain tropic zone, which may provide theoretical reference for improvement of physical fitness of different ethnic college students. Method: physical fitness index was tested on the basis of the latest revision of national student physical health standard in 2014, and physical fitness test data were analyzed by SPSS 16.0 software. Results: there are no significant differences of physical characteristics and nutritional condition between Li and Dai college students (P > 0.05), and no significant differences of speed quality and lumbar abdomen power (P > 0.05), but the cardiopulmonary level and endurance quality of Li college students are higher than Dai college students (male: P<0.01; female: P<0.05). Conclusion: two tropic zones have similar geographical environment, social economic production and dietary habits, so there are no significant differences of physical characteristics and nutritional condition of body between Li and Dai college students. Compared with Li college students, Dai college students live and study in high altitude area which affected by low supply of oxygen, and this may cause the oxygen uptake and cardiopulmonary function level of Li college students are higher than Dai college students. Bamboo dancing of Li nationality runs through the whole process of teaching, so male Li college students’ long-term training of beating bamboo posts with sticks lead to great upper body strength, and the bamboo dancing also lead to good flexibility and jumping ability of Li college students.
