海南省文昌县滨海红砂土为第四纪海相沉积物发育形成,分布颇广,面积190.22km~2,占全县土地面积2346km~2的8.11％。地貌上表现为滨海沉积台地的盖层和海岸堆积阶地,分布部位高,土色赤红,土层深厚,植被覆盖处疏松,裸露处紧实,粉砂含量偏大,水土流失严重,寸草不生,水土流失面积达121.4km~2,占红砂土面积的63.82％。 为了摸清滨海红砂土水土流失的成因和探索其综合治理途径和措施,1979年下半年,在红砂土水土流失严重区域的乌土坡建立了文昌县水土保持站,开始了综合治理红砂土水土流失的实践。
The coastal red sand in Wenchang County, Hainan Province, developed and formed Quaternary marine sediments, covering an area of 190.22km 2, accounting for 8.11% of the total land area of the entire county of 2346km 2. The topography of the coastal sedimentary platform is the cap rock and coastal accumulation terrace. The distribution area is high with red soil color, deep soil layer, loose vegetation cover, compact bare area, large silt content, serious water and soil loss, Drainage area of 121.4km ~ 2, accounting for 63.82% of the area of red sand soil. In order to find out the causes of the soil erosion of red sandy soil and explore its comprehensive treatment approaches and measures, in the second half of 1979, Wenchang County Soil and Water Conservation Station was established in Wutipo, where soil erosion of red sand soil was serious, Soil and Water Loss Practice of Sandy Soil.
