摘要:

采用样方调查法和粪便显微组织学分析法确定夏秋两季神农架地区川金丝猴的食物组成,分析主要食源植物的营养成分,探讨影响川金丝猴夏秋季节取食的主要因素。结果表明: 夏季,川金丝猴食物组成与食源植物的相对丰富度(r=0.656,P=0.000)、含水量(r=0.078,P=0.609)、粗脂肪含量(r=0.020,P=0.896)、无氮浸出物含量(r=0.238,P=0.115)呈正相关,与食源植物的粗蛋白含量(r=-0.113,P=0.459)、粗纤维含量(r=-0.144,P=0.347)、粗灰分含量(r=-0.156,P=0.305)呈负相关; 秋季,川金丝猴食物组成与食源植物的相对丰富度(r=0.703,P=0.000)、含水量(r=0.258,P=0.176)、粗脂肪含量(r=0.291,P=0.125)、粗蛋白含量(r=0.537,P=0.003)、粗纤维含量(r=0.194,P=0.312)、粗灰分含量(r=0.308,P=0.104)呈正相关,与食源植物的无氮浸出物含量(r=-0.546,P=0.002)呈负相关。通过主成分分析可知: 食源植物的无氮浸出物(0.936)、粗纤维(0.886)和粗灰分(0.870)为川金丝猴夏季取食的主要影响因子; 而食源植物的粗纤维(0.968)、粗蛋白(0.948)和相对丰富度(0.877)为川金丝猴秋季取食的主要影响因子。

Abstract:

In order to find out main factors influencing the feeding of golden monkey(Rhinopithecus roxellana)in Qianjiaping, Shennongjia Nature Reserve, summer and autumn food composition was investigated through quadrat survey and histological analysis of plant remains in feces. The analysis included nutritional components, relative abundance and relative density in the feces. The results showed that, in summer, food composition of Rhinopithecus roxellana was positively correlated to the relative abundance(r=0.656, P=0.000), water content(r=0.078, P=0.609), crude fat content(r=0.020, P=0.896)and the nitrogen-free extract content(r=0.238, P=0.115)of food plants, and negatively correlated to crude protein content(r=-0.113, P=0.459), crude fiber content(r=-0.144, P=0.347)and crude ash content(r=-0.156, P=0.305)of food plants; Food composition in autumn had positive correlation with the relative abundance(r=0.703, P=0.000), water content(r=0.258,P=0.176), crude fat content(r=0.291,P=0.125), crude protein content(r=0.537, P=0.003), crude fiber content (r=0.194, P=0.312)and crude ash content(r=0.308, P=0.104)of food plants, and negative correlation with the nitrogen-free extract content(r=-0.546, P=0.002)of food plants. Principal component analysis suggested that nitrogen-free extract(0.936), crude fiber(0.886)and crude ash(0.870)were the main affecting factors in summer, whereas rude fiber(0.968), crude protein(0.948)and food abundance(0.877)were the main factors in autumn.
