云南森林自然中心森林资源现状分析与评价

摘要

In order to manage the forest resources reasonably and scientifically,give full play to the maximum efficiency of existing forest resources,and achieve the sustainable and healthy development of forestry,this study investigated the existing forest resources of Yunnan Forest Nature Center.By analyzing and evaluating the present situation of existing forest resources of Yunnan Forest Nature Center,the results showed that:1) The unit stock volume of the existing forest resources of Yunnan Forest Nature Center was high (102.1 cubic meters per hectare);2) The stand structure is irrational,the coverage of artificial forest was accounted for 80.41％ of that of total forest,the proportions of half-mature stand and near mature stand were high (68.85％ and 70.09％,respectively),Percentage of coniferous species was high (65.68％);3) The forest reserve resources was abundant.The area of young and middle aged stand was accounted for 55.53％ of the total stand area of high-forest.In additional,the area of afforestation for undeveloped forest,bald woodland,barren hills and wasteland (suitable for afforestation)was 190.6 hm2,it has the great development potential.Therefore,several suggestions were given to resolve the problems discussed above.%为科学管理、合理经营森林资源,充分发挥现有森林资源的最大效益,实现林业健康、可持续发展,以云南森林自然中心现有森林资源为调查对象,通过对森林资源现状调查和分析,客观评价现有森林资源现状.结果表明,云南森林自然中心现有森林资源单位蓄积量较高,公顷蓄积达102.1 m3/hm2;林分结构不够合理,人工林比重大(占80.41％),中龄林、近熟林比重大(占68.85％和70.09％),针叶树种比重大(占65.68％);森林后备资源较为丰富,幼龄林、中龄林面积占乔木林分面积的55.53％,加之人工造林未成林地、其它无立木林地、宜林荒山荒地共有190.6hm2,发展空间较大;针对存在的问题,提出相应的森林经营措施和建议.
