A conjoint analysis was done in this study on the survey of 975 chicken consumers in the Niger Delta Region of Nigeria, between March and September, 2014 to valuate consumers, preferences and willingness to pay （WTP） for various chicken attributed parts, production method, processing method, storage method, the presence of flavor and cooking method. The estimates of consumers, WTP premium prices for various mixtures of value-added characteristics were ascertained. The consumers preferred chicken products refrigerated, from chicken produced under free-range management, chicken breast, chicken product that was addictive and flavor free, which could be oven-heated or pan heated. One half of the entire respondents were willing to pay about 25% more for value-added chicken product over the price for conventional products. On the whole, a premium for value-added chicken products was more likely to be paid for by young consumers, consumers who patronized farmers＇ markets and preferred free-range or organic chicken products. WTP by consumers was negatively affected by price of products. The poultry industry could utilize combined knowledge of consumers＇ WTP for value-added chicken product price as a guide of develop innovative value-added chicken products.展开更多
利用桂西南地区不同类型马尾松和栎林的冠层可燃物、地表可燃物、立地条件和气候因子等调查数据,运用Behave Plus 5.0.5和Consume 3.0模型,分析不同林型林火行为趋势,并计算各林分过火后可燃物消耗量和含碳类气体排放量。结果表明:不同...利用桂西南地区不同类型马尾松和栎林的冠层可燃物、地表可燃物、立地条件和气候因子等调查数据,运用Behave Plus 5.0.5和Consume 3.0模型,分析不同林型林火行为趋势,并计算各林分过火后可燃物消耗量和含碳类气体排放量。结果表明:不同林分可燃物载量分布差异显著,马尾松纯林在风速大于15 m·s-1时,极易由地表火转化为树冠火,马尾松-红锥-潺槁树林在风速大于20 m·s-1时,极易转化为树冠火,马尾松-石栎林、石栎-马尾松林和大叶栎纯林可形成地表火,但不易发生树冠火。研究可为进一步了解森林火灾对区域气候变化的影响提供基础数据。展开更多
