关于赣南和江西省的水土流失的现状与历史,流失原因及其前景,经过实地考察,着重说明以下三种情形: 一、水土流失面积还在继续扩大,加速升级。全省流失面积,据解放初期统计为1,650万亩,1964年即扩大到2,700万亩,平均每年以75万亩的速度增加,而到1981年流失面积已达到5,753万亩,净增3,053万亩,平均每年以190万亩的速度增加。再看兴国县:经过去年51个单位90人的按图查对计算,从1964年流失237万亩增加到1981年的284万亩。该县的严重流失(强度和剧烈)的比率也从1964年的35.24%上升到1980年的49.6%。不少海拔300—800米的高山,竟然也成了严重流失地带。现在,赣南的流失面
With regard to the status quo and history of soil and water loss in Jiangxi Province and Jiangxi Province as well as their causes and prospects, after field investigation, the following three situations are highlighted: I. The area of soil and water loss is still expanding and accelerating its upgrading. The area lost in the province was 1,650 million mu in the initial period of liberation and 27 million mu in 1964, an average annual increase of 750,000 mu. By 1981, the lost area had reached 5,753 mu, a net increase of 30.53 million mu , With an average annual increase of 1.9 million mu. Look at Xingguo County: After 51 units last year, 90 people calculated according to the diagram, from 237 million mu loss in 1964 to 2.84 million mu in 1981. The county’s serious loss (intensity and severity) also rose from 35.24% in 1964 to 49.6% in 1980. Many altitudes of the mountains of 300-800 meters, even has become a serious loss zone. Now, Gannan lost face
