| 摘 要： | 平顶山市丘陵区面积２６０７．３６ｋｍ＾２占总面积的２９．６％，该区沟壑纵横，地形支离破碎，水土流失严重，特别是风化层较厚的花岗岩，片麻岩及黄土覆盖丘陵区，沟蚀极为发育，冲沟密布，沟头前进，沟岸扩张，沟床下切，崩塌滑坡，致使沟道荒芜。沟头是沟道与坡面之间由缓变陡的转折处，是沟掌与沟道的衔接处，是溯源侵蚀发生与发展的关键部位。沟头防护治理是小流域综合治理的重要组成部分，然而在群众性的水土保持小流域治理

| Abstract: | Based on the analysis of research on forest protecting soil in home and abroad,combining with the characteristics of soil runoff in Hebei Province,the datas were calculated.The soil conservated is 62 661.5 thousand t/a,the decrease of deserting land is 9640.24hm2,preventing of mud and sand 15906.4 thousand m3,depositing mud and sand 11568.4thousand m3,the loss of soil organic matter 2713.2 thousand tons,the loss of N,P and K 1302.4 thousand tons.The total economic value is 3.815 billion Yuan,that means 1957.5Yuan /hm2. |
