This area refers to the size of mountains, hills, undulating terrain, pulling the highest peak of up to 1,600 meters above sea level. A mountain is 200-500 meters high. Among them, the low red sandstone hills in the middle reaches of the Qianjiang River are relatively flat. The soil is yellow tendon. The total area of 9934 mu. Divided into 6 soil section 23 soil group 141 soil species. The main points are as follows: (14) The parent material of Huangdadihu is hilly terraforming into the mountainous yellow soil. Some of the parent materials are Quaternary red earth layers, and the other is the mountainous yellow soil. After being washed and transported by rainwater,岙 or hillside flat parts. Parent material sticky, and more dense, most acidic to strong acid reaction, only a few were neutral or slightly acidic. Its location is mainly mountainous terrain
