From may 2011 to October 2012, we take the landslide’s picture every day of shanping forestroad in 3.5k and shanging river by using wireless sensor network.We analyze the pictures in may 2011, October 2011, April 2012 and October 2012,It reveals that the percentage of green cover from vegetation is 6.86%、17.96%、14.68%及30.5% in shanping forestroad in 3.5k and 13.83%、38.84%、32.09%及75.7% in shanging river. In the landslide of shanping forestroad in 3.5k, the main tree’s component are pioneer species , like Trema orientalis, Mallotus paniculatus, Macaranga tanarius, Hibiscus taiwanensis and Rhus semialata Murr. var. roxbrughiana. It reveals the ecological succession belong to pioneer stage.The important value of Trema orientalis reach to 38.6%(2011/4)、35.02%(2011/10)、34.85%(2012/4)、37%(2012/10). In the landslide of shanping river, the main tree’s component are Mallotus paniculatus , belong to pioneer species , the important value of Trema orientalis reach to 88.77%(2011/4)，89.47%(2011/10),89.53%(2012/4) and 88.65%(2012/10). The main underground vegetation in the landslide of shanping forestroad in 3.5k includes Mikania micrantha and Bidens pilosa va. Radiate, the important value is separately 28.2%(2011/10)、11.95%(2012/4)、15.17%(2012/10) and 12.1242.14%(2011/10)、44.13%(2012/4)、51.59%(2012/10)%、17.53%(2012/4)、23.8%(2012/10), both of them belong to invasive plant. The main underground vegetation in the shanping river is Chromolaena odorata, 442.14%(2011/10)、44.13%(2012/4)、51.59%(2012/10)2.14%(2011/10)、44.13%(2012/4)、51.59%(2012/10), also belong to invasive plant.
From the traditional research of frog , the frog’s species include 13 species, like Rana latouchii, Rhacophorus moltrechti, Chirixalus eiffingeri, Rana kuhlii, Microhyla butleri , Fejervarya limnocharis etc., but we can’t take the voice’s record of Bufo bankorensis and Rana sauteri. The analysis reveals significant effects between temperature and frog voice. Because the Typhoon Morakot the population of Rana kuhlii is zero so far. The population of new frog’s species of Microhyla butleri is getting increasing.
