中文摘要	人类活动强度增大和气候的变化是影响农牧交错带东南边缘农业发展的因素之一，本文应用灰色关联模型，对农牧交错带河北坝上丰宁县土壤风蚀沙化因素进行了分析：发现影响土壤风蚀沙化的主要因素是人口增长率和冬季1月平均气温，其次是耕地、草地面积的变化和夏秋8、9月的降水量。综合来看影响该区土壤风蚀沙化的主要因素是人类活动，自然因素居次要地位。在人口增加和人类活动强度不断加大的情况下，农业生产必须依据冬季平均气温和夏秋降水量的变化来调整结构和生产方式，以减轻土壤风蚀沙化，实现农业的可持续发展。
英文摘要	Increasing intensity of anthropogenic activity and climate change are the main factors of influencing soil eco-environment and then affect the agriculture production process in southeast of farming-pastoral zone of Fengning County. Gray relation model was applied to analyze the main factors of soil erosion and desertification in Fengning county of Hebei Province. The nature factors were of temperature and precipitation, and anthropogenic activities were of population increase rate, per capital income , change of grassland and cultivated land area. The research result indicates; Population increasing rate and January mean temperatures were the main factors of influencing soil erosion and desertification. The second factors were the changes of grassland and cultivated land area. The third factors were precipitation of August and September. From the result we knew that anthropogenic activity was the main factors of influencing soil erosion and desertification. With population growth and increase intensity of anthropogenic activity, agriculture production must be based on January mean temperature and precipitation of summer and autumn. So agriculture production framework and the way should adjust properly according to background of temperature and precipitation changing. If summer and autumn precipitation decreased and January temperature rose, cultivated land area must be reduced next year. Stock raising or other ways of production should be increased. On the other hand, if the summer and autumn precipitation increased and January temperature fell, cultivated land area could be enlarged, because the soils have enough water and are suitable to be cultivated. Adjustment of agricultural production structure according to changes in January temperature and precipitation of summer and autumn can mitigate soil erosion and desertification and guarantee sustainable agricultural development.
