摘要
箱法和微气象学方法是当前用以现场测量陆地生态系统温室气体排放的主要方法。本文较系统地介绍了获得较广泛应用的箱法和主要微气象学法，如涡度相关法、空气动力学法、能量平衡法和质量平衡法等。对各类方法的适用性及其科学局限性进行了比较、简评。最后给出了“内蒙古半干旱草原土壤－植被－大气相互作用”（ＩＭＧＲＡＳＳ）项目中开展温室气体排放（吸收）现场观测方法的选择。
At present, the box method and micrometeorological method are main methods used for in-situ measurements of greenhouse gases emission from terrerstrial ecosystem Widely used box method and some main micrometeoroloyical methods, such as eddy correlation method, air dynamic method, energy balance method and mass balance method and so on are introduced systematically, usefulness and scientific limitation for various methods are compared in this paper Methods for in-situ measurements of greenhouse gases emission from grassland in the project on the Inner Mongolia Grassland Atmosphere Surface Study (IMGRASS) are also recommended in this paper
