川南退耕丛生竹林枯落物持水特性研究
Study on Water-holding Capacity of Litter Layers in Returning Farmland to Sympodial Bamboo Forests in Southern of Sichuan Province
摘要
Abstract
To investigate the litter amount and water-holding capacity under de-farming bamboo forests, Dendrocalamus （D） farinosus, Bambusa （B） pervariabilis ）〈 Dendrocalarnopsis （D） daii 3 and Bambusa （B） rigida, taking from Changning County of Sichuan Province, were determined in this paper. It could be con- cluded that thickness variation was from 33 mm to 51 mm and the litter amount changed from 6.88 t/hm~ to 9.46 t/hm2 under three different types of bamboo plantations. Litter amount of D farinosus was the most and that of B. pervariabilis X D. daii was the least. Results also showed that dynamic changes of water- holding capacity, water absorption rate and immersion time of different litter was similar. The rapid changes were observed within 0-2 h, and then it slowly changed in the following six hours. The change stabilized after 8 h. Water-h01ding capacity, interception rate and the effective interception rate of D. farinosus were the best and the values were 36.52, 32.53, 27.05 t/hm2, respectively. The next wasB. rigida （30.33, 28.33, 23.83 t/hm2） and the last wasB. pervariabilisXD, daii （28.35, 25.89,21.63 t/hm2）.关键词
