摘　　要： 本文研究中国石龙子（Ｅｕｍｅｃｅｓｃｈｉｎｅｎｓｉｓ）腹脂肪体、肝脏、去尾躯干和尾等主要脂肪贮存部位。育肥、禁食以及越冬后至繁殖期的３月、４月和５月份组个体的脂肪体系数和肝脏系数组间差异显著；去尾躯干、尾和肝脏、脂肪含量组间差异显著。禁食濒死个体的脱脂去尾躯干和尾灰分含量明显大于育肥个体，未经灰分校正能值明显小于育肥个体，经灰分校正能值与育肥个体相近。濒死和育肥个体的脱脂肝脏灰分含量和能值差异相对较小。腹脂肪体和尾部脂肪贮量大，且其中的贮存和动用活跃，为该种动物最主要的脂肪贮存部位。体内贮能的极度消耗是禁食中国石龙子死亡的重要原因。育肥可使动物各脂肪贮存部位迅速积累脂肪。 The major lipid reserves were studied for the skink Eumeces chinensis collected from a field in Hangzhou. The skinks were divided into five groups, i. e.March, April, May,fast, and fed-up groups. Data collected over a three-year period indicated that there were significant differences in fatbody indices, liver indices,and lipid contents of carcass, tail,and liver among skinks of different groups.Lipid reserves were reduced from the time of emergence from winter dormancy to the breeding season. The most important lipid reserves of the skink were tail and abdominal fatbody, because the most active lipid storage and utilization occurred at the two sites. In addition, the two sites alone comprised most of the standing lipids in an individual. The fast skinks had apparently higher ash contents but much lower ash uncorrected caloric values of lean carcass and lean tail than the fed-up individuals. No obvious differences in ash-free caloric values of lean carcass and lean tail were found between fast and fed-up skinks. There were relatively slight differences in ash content and caloric value of liver between fast and fed-up skinks. One of the major reasons which put the fast skinks to death was the exhaustion of stored materials.When skinks were allowed to feed freely on larvae of Tenebrio molitor, all major lipid reserves could rapidly store lipids.
