高山峡谷地区无线电遥测与GPS空间定位的比较:野外放归大熊猫的跟踪定位
Comparison of spatial positioning between radio telemetry (RT) and GPS in temperate mountain forests: A case study on tracking the reintroduction of captive giant pandas
摘要
Abstract
This study was conducted on the first reintroduced giant pandaf "Xiangxiang" ) that was monitored using a jointly equipped global positioning system (GPS) and radio telemetry (RT) collar ( Lotek GPS_ 4400M) at Wuyipeng Panda Observation Station in Wolong Nature Reserve, China. We diurnally monitored the health status, movement patterns and foraging behaviors of the giant panda in an area of natural habitat from April 2006 to February 2007. We calculated the index of spatial positioning efficiency ( SPE) , recorded topographic indices, and estimated spatial positioning differences (SPD) , home range size and daily travel distance. Differences between results from the different two tracking methods were compared to show their feasibility and validity in this temperate mountain forest region. The results are as follows; SPEs of RT-acquired data significantly exceeded those of GPS-acquired data (P < 0. 001). The RT-acquired SPEs were 54. 1% ( plotting method) and 45. 2% ( g 2D) , respectively. SPEs of RT and GPS-acquired data were significantly dif- ferent across different months (P < 0. 05) , which may relate to different altitudes and animal foraging patterns across different months. Slope of RT-acquired data was higher than GPS-acquired data, and aspect and altitude of RT-acquired data lower than GPS-acquired data. No significant difference was found between the two radio telemetry methods (triangle method and plotting method) (P > 0. 05). The distances between points ( SPD) acquired from the two different methods on the same day averaged 450 - 660 m. The home ranges derived from RT-acquired data exceeded that of GPS-acquired data, with the exception of the months of May, Sept. and Dec. , for which there was no significant difference between RT and GPS methods (P > 0. 05 ). Daily movement distances were significantly greater for RT-acquired data than GPS-acquired data (P<0. 05) , with the exception of December 2006. All indices derived from two different radio telemetry methods were not significantly different (P >0. 05). We conclude that both the radio telemetry (RT) and GPS monitoring methods are feasible in our study area and the joint RT/GPS collars provide valid data in temperate mountain forests, especially for monitoring habitat use.关键词
