前不久,我们对阿克苏、巴州两地区的人工林和木材市场作了些调查,从调查中感受到有些问题需提出来供大家参考。 一、据阿克苏地区林业处统计截止1987年全地区人工林面积84万亩,蓄积量73万立方米,其中防护林面积30万亩,蓄积量为52万立方米,用材林面积10.14万亩,蓄积量为21万立方米。全地区防护林和用材林中,幼林面积为27万亩,蓄积量13万立方米,中幼林面积6.4万亩,蓄积量为30万立方米,近熟林面积6.2万亩,过熟林面积0.48万亩,蓄积量为27万立方米。以上数字说明,全地区防护林和用材林中,幼林面积最大占67％,过熟林面积最小,只占1.6％。
Not long ago, we conducted some surveys on plantation and timber markets in Aksu and Bazhou. We found some problems from the survey to be put forward for reference. According to statistics from the Aksu Forestry Department, the total area of artificial forests in the whole region was 840,000 mu in 1987, with an accumulated volume of 730,000 cubic meters. Among them, 300,000 mu of shelterbelts were stocked and 520,000 cubic meters were planted. The area of timber forests was 101,400 mu, 210000 cubic meters. The shelterbelts and timber forests in the whole region have a young forest area of 27 mu, a stock volume of 130,000 cubic meters, a middle-aged and young forest area of 64,000 mu, a stock volume of 300,000 cubic meters, a near-mature forest area of 62,000 mu and an over-mature forest area of 48,800 Mu, volume of 270,000 cubic meters. The above figures show that in the whole region shelterbelts and timber forests, the largest area of young forest accounted for 67%, over-mature forest area is the smallest, only 1.6%.
