查询词典 rainfall

When big, moderate rain and rainstorm, the Y value size order is always the masson pine pinus elliottii mixed forest＜the wetland pinery＜the wetland pinery＜the locust tree forest＜the locust tree pinus elliottii mixed forest＜the thin forest, to the soil protection effect, the conifer forest is better than broad leaved forest. For annual rainfall erosion, the Y value ordered: Locust tree forest＜wetland pinery＜locust tree pinus elliottii mixed forest＜wetland pinery＜masson pine pinus elliottii mixed forest＜thin forest.

全县总土地面积4885平方公里，气候特色为春季干燥风沙多，夏季短促降雨少，年平均气温2.5℃，降水量350mm左右，无霜期110天左右，是典型的旱作农业县，长期以来，由于沿袭传统的铧式犁耕作，大量地表完全裸露，季风来临，将土壤中的细沙面土及有机质刮走，造成土壤沙化、肥力下降，沙尘扬起，年复一年，沙化日趋严重，造成生态环境逐年恶化，也决定了当地的农业生产条件，地下水源严重不足，十年九旱，广种薄收，作物产量低而不稳。
