我省川中浅丘农区,地少人多,一般25度以上的坡地都开垦种粮,成片的造林地很少。大于30亩以上的宜林地不到5％〔1〕,森林复被率仅1—3％,用材和烧柴缺乏,水土流失严重。过去人们认为,川中浅丘农区农业用地人平只有一亩左右,那有更多地可以造林。为了解川中农区土地利用情况,究竞有多少土地可以造林,和怎样造林的问题。我们选择了位于川中腹地的资阳县太平公社进行调查,现将结果整理如下:
Hilly area of shallow Sichuan hilly farming, less people and more, generally more than 25 degrees of slope are reclaimed grain, into a piece of afforestation very little. Larger than 30 acres of less than 5% of the forest land 〔1〕, the rate of forest rehabilitation was only 1-3%, the lack of timber and firewood, soil erosion is serious. In the past, people thought that there was only about one acre of agricultural land for people in the shallow-hill farming area in the central part of Sichuan, so that there could be more afforestation.
