| 摘 要： | 利用遥感技术与地理信息系统技术的结合 ,对江西省兴国县和余江县的土壤侵蚀状况进行了时空变化研究。研究结果表明 ,兴国县和余江县的土壤侵蚀状况 ,在侵蚀面积和程度上 ,都在明显改善 ;两县土壤侵蚀面积百分数的缩小量几乎相等 ,但兴国县缩小的比例较余江县小。但就总的情况看 ,土壤侵蚀仍是一个突出问题 ,值得重视

| Abstract: | As Jiangxi Province stands out for its serious soil erosion in the hilly red soil region of South China, research on its spatial and temporal changes was of true typicality. The combination of the remote sensing technique with the geographic information system technique showed significant advantages in the research. By using this technology, the change in soil erosion was studied in Xingguo and Yujiang of Jiangxi Province, with results indicating that soil erosion in the counties was gradually getting under control, both in area and in extent. The decreases in soil erosion area of the two counties were almost equal in percentage, with Xingguo County lagging slightly behind Yujiang County. However, soil erosion was still an outstanding problem in these counties. |
