Indices and criteria of highly effective and multi-functional management of windbreaks/shelterbelts in northeast China

Abstract

Abstract: From the two scales of single shelterbelt and networks as research object, this paper constructed the indices system of highly effective and multi functional m a nagement of shelterbelts/windbreaks. Through analyzing the mechanism relationshi p among every index, 9 main evaluation indices of shelterbelts/windbreaks were p ut forward. For single shelterbelt, there are 6 indices can be used for measurin g management state of shelterbelt, such as porosity, effective protection distan ce, initial protection maturity age, total protection maturity period, ratio of output to invest, and regeneration pattern. For networks system, there are 4 ind ices can be used for measuring management state of networks such as ratio of she lterbelt to patch, networks connectivity, networks ring, and networks dominance. According to quantitative boundary of main indices, the criteria of highly effe ctive and multi functional management of shelterbelts were brought forward. The s e indices and criteria, which become as foundation of measuring sustainable mana gement and direct highly effective management of shelterbelts/windbreaks, can be used to evaluate the management of shelterbelts, not only in distribution of ne tworks but also in structure of single belt.
