我省山地主要由燕山、太行山两大山脉组成。燕山近于东西走向亘于我省北部,太行山屹立于我省西缘。我省山地多在2000米以下,且是孤峰状态。山地农业气候资源的特点是:立体性、多样性、复杂性。山区由于地理位置和地形条件不同,各地热量条件有明显的差异。据初步考察,我省0℃以上积温随纬度的增加而减少,平均纬度每增加
Mountain in our province mainly consists of Yanshan, Taihang Mountain two mountains. Yanshan near the east-west in the northern part of our province, the Taihang Mountains stand in the western edge of our province. Mountain more than 2,000 meters in our province, and is isolated state. Mountain agricultural climate resources are characterized by: three-dimensional, diversity, complexity. Due to the difference of geographical location and topography in mountainous area, there are obvious differences in the thermal conditions of different places. According to the preliminary investigation, the accumulated temperature above 0 ℃ in our province decreases with the increase of latitude, and every increase of average latitude
