中文摘要	贵州毕节石桥小流域与关岭木工小流域处于石漠化严重、坡耕地比例高、粮食产量低且不稳定、人口密度大、农业经济水平低的喀斯特山区. 通过对研究区人口增长的预测,利用人-地关系平衡模型,计算出该两小流域需保有的耕地量分别为281.91hm~2、228.68hm~2. 但由于需保有的耕地面积较未出现石漠化耕地面积大,致使需保有的耕地中仍有部分地存在石漠化. 但如果对这部分石漠化土地都实施退耕还林还草,将无法保障流域内农民的口粮需求. 为此,对该两小流域耕地石漠化区域开展包括林农间作、粮草间作、坡改梯等治理措施. 结果流域内耕地的石漠化得到了有效控制,土壤侵蚀模数由2007年的721.63t/(km~2· a)、42.42t/(km~2·a)下降到2009年的472.78t/(km~2·a)、35.59t/(km~2·a),植被覆盖率分别提高11.3%、6.4%,人均经济收入分别增加300元和231元,不仅有效地治理了石漠化耕地,而且农民生计也得到了保障
英文摘要	Shiqiao Basin in Bijie City and Mugong Basin in Guanling City in Guizhou Province are karst rocky mountain areas with strong rocky desertification, high density of population, and low and instable grain yield as well as low agricultural economic level. Through forecasting the increase trend of the population and using the human-land balance model, the necessary farmlands for these two basins have been counted as 281. 91hm~2 and 228. 68hm~2, However, the area of necessary farmland is larger than non-desertification farmland, which leads to rocky desertification still appear in the farmland. If the grain for green project has been carried out in this place, it will not meet the need for food. Therefore, the measures as intercropping of trees and crops, crop-grass intercropping, reforming sloping fields to terraced fields have been carried out. As a result, rocky desertification has been controlled and soil erosion modulus of the two basins has decreased from 721. 63t/(km~2 · a) and 42. 42t/(km~2 · a) in 2007 to 472. 78t/(km~2 · a) and 35.59t/(km~2 · a) in 2009, vegetation covered lands have increased by 11. 3% and 6. 4%, per capital income has increased by 300 Yuan and 231 Yuan. Rocky desertification has been controlled as well as peasants’ have got much more livelihood safety
