- 摘要:
- 对比分析两次土壤侵蚀遥感调查结果显示：河北省山区极强度和强度土壤侵蚀得到了有效遏止，极强度侵蚀面积减少了818.22 km2，强度侵蚀面积减少了4 293.38 km2；中度和轻度土壤侵蚀面积呈增加趋势，中度土壤侵蚀面积增加3 314.86 km2，轻度土壤侵蚀面积增加6 153.9 km2；河北省山区土壤侵蚀总面积增加，轻度以上的土壤侵蚀面积增加4 357.16 km2。张家口市土壤侵蚀变化比较明显，极强度和强度土壤侵蚀面积明显减少，减少了3 646.46 km2，而中度和轻度侵蚀面积大幅度增加，增加了9 599.69 km2，轻度以上的土壤侵蚀面积增加了5 953.23 km2。
- Abstract:
- In contrast with the result of two remote sensing soil erosion,the conclusion is:the utmost heavy soil erosion and heavy soil erosion had been hold back in mountain area of Hebei Province.The area of the utmost heavy soil erosion has been cut down 818.22 km2,and area of heavy soil erosion 4 293.38 km2.The area of moderate soil erosion and light soil erosion has continually expanded,the moderate soil erosion added 3 314.86 km2,the light soil erosion added 6 153.9 km2.Total area of soil erosion in mountain area of Hebei Province extended.The area above the light soil erosion added 4 357.16 km2.The soil erosion in Zhangjiakou changed markedly.The area of the utmost heavy soil erosion and heavy soil erosion diminished markedly,lowering 3 646.46 km2.The area of the moderate soil erosion and light soil erosion spreaded largely,adding 9 599.69 km2.The area above the light soil erosion added 5 953.23 km2 in Zhangjiakou.
