摘要: 人口、资源和环境之间存在着相互依存、相互影响的关系。对于生态条件有极限的内蒙东部半干旱地区,人口、资源、环境之间的这种制约关系表现得更为明显。由于人口的大量增长,使得内蒙东部沙漠化不断发展。1)人口大量增加,使人均占有土地资源减少,主要表现在草原开垦和撂荒;2)伴随人口增长而盲目增加牲畜头数,使草场超负荷;3)人口的大量增加,造成能源不足,使得当地居民无控制地大量樵柴和掠夺式地砍伐各种植物。作者认为:推行计划生育政策使人口繁殖控制到规划的范围以内是提高环境质量和人口素质的重要对策。除此之外,在沙漠化地区采取积极恢复环境措施改善环境质量扩大人口载容量也是调整人口、资源、环境之间不协调关系的积极途径。诸如调整农、林、牧结构扩大工、商、服务业的比重,减少对土地依附性强的农林牧比重,修建水利工程变旱作农田为灌溉农田等。

Abstract: Human population, resources and environment are interdependent and interacted. This restrictionship can be seen in the semi-arid zone in eastern Inner Mongolia where the ecological condition is limited. Population growth brings unceasingly spread of desertification in eastern Inner Mongolia. Population growth causes a) decrease of average acreage of arable land for each man due to the reclaim of rangeland and abandonment of infertile farmlands;b) blind increase of animal number and over-loading of range-lands;c) insufficiency of energy fuel and d) uncontrolled cutting of herb plant.It is considered that the policy on family planning and birth control is one of the fundamental strategies arid suitable to the national situation in China and it should be carried out continueously. Furthermore, positive measures should be adopted to renew the degraded environment in the de-sertified areas.The improvement of environmental quality and the increase of human population carrying capacity of land are also the positive ways to fifl thegaps amongst the human population, resources and environment, It is suggested that the land use should be changed and its structure for cropping, reafforestating and animal grazing should be reorientated; the proportion of industry, trade and service interprises at small scale should be developed and rain-fed agriculture should be replaced with irrigation; poor management of land should be stopped.
