摘　　要：以滇中地区的紫荆泽兰茎为研究对象,测定了紫茎泽兰茎的粗脂肪含量、灰分含量、热值以及紫荆泽兰根系土壤有效磷含量。以粗脂肪含量、灰分含量以及热值为评价指标,计算了紫茎泽兰茎的燃烧性综合指数,并分析了紫茎泽兰粗脂肪含量、灰分含量、热值以及燃烧性综合指数与土壤有效磷含量的关系。研究表明,紫茎泽兰茎的粗脂肪含量、热值以及燃烧性综合指数与土壤有效磷含量呈正相关关系的比例分别为65.22%、52.17%和56.52%,灰分含量与土壤有效磷含量呈负相关的比例为60.87%。土壤有效磷含量可在一定程度上增加紫茎泽兰茎的粗脂肪含量、热值,降低其灰分含量,并增强其燃烧性。There are a lot of phosphate resources in central Yunnan,at the same time,it is also the distribution area of Eupatoriumadenophorum and forest fire in Yunnan.It can provide a scientific basis for understanding the fire distribution characteristics in central Yunnan and reasonable choice combustible management and forest fire control methods by studied the relationship between the combustibility of Eupatoriumadenophorumstems and the soil available phosphorus content.And 23 batches of Eupatoriumadenophorumstems,which is from Anning city,Chengjiang county,Dongchuan district and so on,were selected as the research object,and determined the crude fat content,ash content,calorific value of the Eupatoriumadenophorumstems and the available phosphorus content of the root soil of Eupatoriumadenophorum.And calculated the combustibility index of Eupatoriumadenophorumstems by the crude fat content,ash content and calorific value,and analyzed the relationship between soil available phosphorus and crude fat content,ash content,calorific value,combustibility index.The research has shown that the ratios of crude fat content,calorific value and comprehensive index of combustibility positively correlated with soil available phosphorus content were 65.22%,52.17%,and 56.52%,respectively,and the ratio of ash content negatively correlated with soil available phosphorus content was 60.87%.Andsoil available phosphorus content can increase the crude fat content and calorific value of Eupatoriumadenophorum stem to a certain extent,reduce its ash content,and increase the combustibility to a certain extent.
