对广西马山县岩溶地区进行2次石漠化监测,结果显示:马山县岩溶土地面积162935.3hm2,其中石漠化演变类型中稳定型面积143387.3hm2,顺向演变面积16273.5hm2,逆向演变面积3274.5hm2,石漠化状况得到较好的改善。石漠化土地转变为潜在石漠化土地变化量最大;石漠化顺向演替最重要因素是石漠化综合治理;石漠化逆向演替最重要因素是人为因素。
對廣西馬山縣巖溶地區進行2次石漠化鑑測,結果顯示:馬山縣巖溶土地麵積162935.3hm2,其中石漠化縯變類型中穩定型麵積143387.3hm2,順嚮縯變麵積16273.5hm2,逆嚮縯變麵積3274.5hm2,石漠化狀況得到較好的改善。石漠化土地轉變為潛在石漠化土地變化量最大;石漠化順嚮縯替最重要因素是石漠化綜閤治理;石漠化逆嚮縯替最重要因素是人為因素。
대엄서마산현암용지구진행2차석막화감측,결과현시:마산현암용토지면적162935.3hm2,기중석막화연변류형중은정형면적143387.3hm2,순향연변면적16273.5hm2,역향연변면적3274.5hm2,석막화상황득도교호적개선。석막화토지전변위잠재석막화토지변화량최대;석막화순향연체최중요인소시석막화종합치리;석막화역향연체최중요인소시인위인소。
According to the results of monitoring at twice, the karst area of Mashan County was 162 935.3 hm2, of which the stable area was 143 387. 3 hm2, and the succession area was 16 273.5 hm2, and the reverse succession area was 3 274. 5 hm2. The status of rocky desertificafion was greatly improved. The variation of rocky desertification land turning to potential rocky desertification ]and was the most, and the most important factor of succession was complex rocky desertification management, while human factor was the most important factor of reverse succession.
