Deficient resource means resources insufficiency because the demand has exceeded the supply in a certain temporo-spatial scope and under certain economic and technical condi -tions.According to the classification of deficient resources,oil,cultivated land and fresh water are strategic deficient resources,which have a great impact on social-economic development and national security in China.Forest,rich iron ore,chromite,copper and sylvite are non-strategic deficient resources.With economic development and growth of population,the amount of short-age of the above-mentioned resources will increase and deficient level will be intensified during the period from the beginning to the mid21st century.In order to solve the problem compre-hensive measures should be implemented:(1)meeting the demand of deficient resources by us-ing foreign resources through various channels;(2)establishing resources strategic reserve for dealing with resources crisis;(3)reducing resources consumption by saving,replacing and com-prehensive utilizing;(4)resources improving the capacity of renewable resources by strengthen-ing protection of renewable resources;and(5)seeking for new ways to solve the shortage prob-lems based on the innovation of science and technology.
