有蹄类营养生态学研究进展

有蹄类动物营养生态学是一门正在兴起的新学科,是现代生态学领域研究动物食物数量和质量、营养适应以及营养对种群特征作用规律的分支学科.动物种群和其环境中食物资源的相互关系及作用机理构成了这一学科的基本研究内容.本文从食性分析、营养状况评价、食物营养质量评价、消化与能量代谢、取食行为、营养容纳量和营养生态位等主要方面对这一学科进行了探讨.

Advances in the study of nutritional ecology of ungulates

The nutritional ecology of ungulates is a rising subject,which is also a branch subject that mainly studies on the quantity and quality of food for animals,the nutritional adaptation and the functional mechanism of population characteristics of nutrition.The basic contents of this subject are composed of the interrelationships and the action mechanisms between the ungulate population and food resources in their environments.In this paper,We reviewed the advances in the study of nutritional ecology of ungulates from the following aspectsthe food habits,the evaluation of the nutritional condition and food nutritional quality,the digestion and energy metabolism,the foraging behavior,the nutritional carrying capacity and the trophic niche.
