| 摘 要： | 农业用地的面积和分布变化受多种因素的影响。有自然因素也有人文因素,而更直接的影响因素是人类土地利用活动。通过对四子王旗农业用地变化情况研究,结果表明：近十年来四子王旗农业用地面积基本保持不变,占总面积的94.3%。旱地、天然草地和未成林造林地三者变化面积占四子王旗土地变化面积的96.67%。科技进步在农业用地变化中主要表现在大中型机械的使用,其数量的变化是农业用地变化过程的主要驱动力。

| Abstract: | The area and distribution changes of agricultural land are affected by various factors. There are natural factors and cultural factors, and more direct impact derived from human land-use activities .Through the study of agricultural land changes in Siziwang banner, the results show that in the past decade, agricultural lands keep basically unchanged in Siziwang banner, accounting for 94.3% of the total land area. The change area of dry land, natural grassland and immature forest account for 96.67% of land c... |
