摘要

在评述黄土高原地区小流域能量投入产出现状和国内外有关研究动态的基础上

分析了研究地区基本自然条件和能量投产情况

并制定了该区小流域能量流分析程序

包括确定范围、划分和调查子系统、能量计算、指标分析及能流图绘制。以黄家二岔小流域为研究对象

设定了小流域系统的基本结构和能量流分析方法。

Abstract

Based on the reviewing of the current research state of energy input and output at small watersheds in loess plateau region and the study conditions abroad and in home

the basic conditions in nature and input-output of energy in the study area were analysed

from this the study procedure for energy flow analysis was set.which includes scope determination

subsystem division and survey energy calculation

indices analysis and energy flow figure.Taking Huangjia Ercha watershed as a research subject.the capital structure of small watershed system was established and the calculating method for energy flow was made.
