摘要: 研究了香港和广东大多数植物燃料品种的热值和养分浓度,以及评价它们的燃料品质.木本热值为17.13~23.51kJ·g-1,而草本热值为15.13~21.47kJ·g-1.在广东和香港,常用作燃料的品种热值超过20kJ·g-1.N浓度越低,越适宜用作燃料,因为坡地生态系统损失的N和排放到大气的NOx少.木本N浓度为4.67~10.90mg·g-1,而草本N浓度为3.55~14.59mg·g-1.高P和高K的品种也不宜用作燃料,因为山坡地的养分损失大.P浓度为0.17~1.05mg·g-1,而K浓度为3.98~23.00mg·g-1.木本与草本品种之间,热值及养分浓度差异都不显著.

Abstract: In this paper, the calorific value and nutrient concentration of most phytofuel species in Hong Kong and Guangdong Province are determined and their quality as fuel is assessed.The calorific value of woody species ranges from 17.13 to 23.51 kJ·g-1 , while that of herbaceous species ranges from 15.13 to 21.47 kJ·g-1 . The species commonly used for domestic fuel in Guangdong and Hong Kong have a calorific value of over 20 kJ·g-1 . Species with lower Nconcentration are more suitable for fuel, because less Nis removed from upland ecosystems and less NOx is emitted to the atmosphere. Woody species have a Nconcentration of 4.67~10.90 mg·g-1 , whereas herbaceous species, 3.55~14.59 mg·g-1 . Pand Kricher species are less desirable fuels, since more nutrients are removed from hillsides. The Pconcentration varies from 0.17 to 1.05 mg·g-1 , and K, from 3.98 to 23.00 mg·g-1 . Woody species are not significantly different from herbaceous ones in calorific value and nutrient concentration.
