林野厅于1987年2月汇总并发表了以本国森林为对象的全国森林资源现况调查(1986年3月31日当时)结果。根据这次调查结果可知,森林面积比1981年减少了2万 ha(0.1%),变为2526万 ha。但是森林蓄积比1981年增加了3亿7800万 m~3(15.2%),达到了28亿6200万 m~3。森林资源的现状:①过去的20年里,森林面积基本上保持原状,如1966年是2517万 ha,1971年是2522万 ha,1976年是2526万 ha,1981年2528万 ha,稍有扩展。随着本国经济的发展,到现在为止虽然毁林造田、建公共及服务设施等,但相反地也将一部分农田和野地等编

According to the findings of this survey, the forest area has decreased by 20,000 ha (0.1%) from 1981 to 25.26 million ha. However, the volume of forest was increased by 378 million m 3 (15.2%) from 1981 to 2.862 billion m 3. The status quo of forest resources: ① The forest area has basically remained the same in the past 20 years. For example, the area of forests was 25.17 million ha in 1966, 25.22 million ha in 1971, 25.26 million ha in 1976 and 25.28 million ha in 1981 with a slight expansion . With the development of our economy, we have destroyed forests and built public facilities and service facilities so far. On the contrary, we have compiled a part of farmland and fields
