每当你由金华出发乘火车或汽车经龙游去衢县,就可以在车窗二侧看到连绵不断的数不尽的砖红色小山丘,在这些小山丘上倔强地生长着稀疏的小松树,其他树木很少看见,还有一些小山丘上至今还是寸草不长,这里就是有名的金、兰、汤红土丘陵盆地。由于山丘上没有植被保护,水土流失非常严重,每逢大雨,洪水挟带着泥沙横冲直撞,毁坏农田,淤塞河 Whenever you take a train or car from Jinhua to Quxian via Longyou, you can see the numerous endless brick red hills on the two sides of the car window, stubbornly grow sparsely small on these small hills Pines, other trees rarely see, there are still some small hill is still not inch of grass, here is the famous gold, blue, red clay hill basin. Due to the fact that there is no vegetation protection in the hills, the soil and water loss is very serious. In the course of heavy rain, floods carry sediment and collide with each other, destroying farmland and silting rivers.
