黑龙江垦区林业次级产业产值灰色关联分析

Analysis of Forestry Secondary Industry Output Value of Grey Correlation in Heilongjiang Reclamation Area

以黑龙江垦区林业第一产业中林木培育和种植业、林产品采集业、林木采运业这3个次级产业为研究对象。依据2004~2015年《黑龙江垦区统计年鉴》数据，运用灰色关联法计算了2003—2014年林业第一产业内部各次级产业产值与林业第一产业总产值的关联度。动态关联度研究结果表明：林木的培育和种植业与垦区林业总产值的动态关联度高于林产品采集业和林木采运业，在国家积极推进天然林保护工程这一背景下，为其他垦区以及黑龙江省农村发展林木的培育和种植业，促进其优势产业发展提供学习的对象。

To forestry in Heilongjiang reclamation area in the first industry of forest cultivation and planting industry, forest products industry gathering and tree mining transport industry in the seconda- ry industry as the research object. According to the data of the year of 2004-2015 ＂statistical yearbook of Heilongjiang＂, using the method of grey correlation degree from 2003 to 2014 Cadillac forestry pri- mary industry, secondary industry output value and forestry total output value of the primary industry association was calculated. Dynamic correlation results show that the dynamic association of forest cul- tivation and planting industry and forestry in Heilongjiang reclamation region output is higher than that of the forest product collection industry and forest harvesting industries, in the country to actively pro- mote the natural forest protection project the background and other reclamation areas and in rural areas of Heilongjiang Province, the development of forest cultivation and planting industry, promote the ad- vantages of industrial development to provide learning objects.
