浙江省山丘面积占总面积的72.8%,其中丘陵面积较多,100～500米高程的丘陵面积约为5000公里~2,占丘陵山地的66.3%,200米以下的低丘有大面积成片的宜垦地可开发,坡度在15度左右,是坡地造田的主要来源,有低丘红壤、玄武岩平台和山麓坡积地等三种类型,其中低丘红壤面积最大,约500万亩,主要集中在金巨盆地。由于土地瘦瘠,水土流失严重,解放前大多为荒芜之地,解放后,才开始开发利用,实践证明,低丘不仅可以发展经济林木,还可发展各类
Zhejiang Province, the total area of 72.8% of the hills, of which more hilly area, 100 to 500 meters elevation of the hilly area of about 5000 km ~ 2, accounting for 66.3% of hills and hilly areas, 200 meters below the hilly area has a large area Reclaimed land should be developed, the slope is about 15 degrees, is the main source of slope farmland, there are red soil, basaltic platform and piedmont slope land and other three types, of which the largest red soil area of about 5000000 acres, Mainly concentrated in the gold giant basin.
