The reserve of ferrous metals in Hengyang is richest in China. The reserve of porcelain clay and the output of albite is also highest nationwide . Fluorite and barite are also famous all around the world, known as “the home of non-ferrous and ferrous” . The most advantaged mineral : lead, zinc and copper of the Non-ferrous metal are in high rank of Hunan province .The reserve of lead is about 135,600 tons. The reserve of zinc is 1,230,000. As for precious metals，the reserve of gold is about 48,143 kilograms, which is the most in Hunan province. The reserve of silver is about 1’825.3 tons . Nickel also occupies a very important place in this category. In non-ferrous, the reserve of albite is 34997,000 tons ,which is much more than other provinces in China. The reserve of  boron is 10,094,000 tons, only second to Liaoning that belongs to the only orefield of regions south of the Yangtze River. Besides the famed “ JiePai soil ”， flake kaolin  of  Leiyang City is the mineral source that is the biggest in South China with a great mining prospect. The reserve of rock salt in chemical materials is 12,400,000. The reserve of glauberite is 40,452,800 tons which is the biggest in Hunan province.

In Hengyang, soil can be divided into azonal soil and zonal soil. It includes 9 kinds of soil, 20 subgenera ，85 soil genus ，261 kinds of soil, and 111 variants. Zonal soil mainly has  mountain meadow soil ，yellow brown soil ，red soil . Azonal soil mainly has Rendzina red lime soil ，purple soil ，paddy soil fluvo-aquic soil. Red soil, purple soil and paddy field cover the main part of Hengyang agricultural area, which are also the soil most possible to be utilized in agriculture. The regional distribution of different kinds of soil are mainly as follows: the red soil’s covering shows a zonal distribution or speckle distribution; the purple soil’s covering mainly shows a web distribution in the middle part of the basin; the paddy field’s covering shows a branch distribution in the flat valley of the river whose height is below 200 meter; the fluvo-aquic soilcovering also shows a branch distribution in the open and flat blank of the river; the covering of a special kind of red soil called Si Jihong mainly show a round distribution on the purple shale. The directional distribution of the different soil mainly shows a ring-shaped combination from the form the surrounding areas to the center of the basin. The area with a height of from 200 meters to 300 meters, consists of Lime soil, sandstone red plate shale and red granite .  Hill ridge impact low-lying place , situated between down land and low mountain transition zone are usually form gley sex paddy soil . The area with a height from 300 to 500 meters , the general slope is 25 to 30. It is mainly made up of Sandstone and plate shale red or red granite . Ridge impact land ,where are in flat hill and has water to irrigation，are usually paddy field soil which can maintain water，while montane is natural red soil . Geologic structure or the Fault Line usually shapes the cold waterlogged paddy field or Ore poison field .

  Recently, according to the project department of Hengshan Science Zone, the first land expropriation and housing demolition of 585 mu(a unit of area) has been basically completed, the science city's overall planning had its approval of municipal government in may, also a 5 square kilometers of control planning and special planning was approved in september. The EPC project of mangrove model area has been officially started at the end of august and there should be 30,000 centiare come into use before year end.   

  Hengshan Science Zone is a developing opportunity for major industries which brought by hengyang municipal committee and government's intention to accelerate the implementation of innovation-driving and development strategies and to seize the mobile internet technology, it is set up to push hengyang industries make change from processing and manufacturing into innovation industries. And it is a new industriral park which regard technical innovation as object, headquarters concentration with economics, high-end manufacturing as dominant, east to Cai Lun avenue, south to the Xiangjiang river, west to Yuelin highway and north to southern third ring road.   

  Hengshan Science Zone will focus on intelligent manufacturing, biological medicine and corporate headquarters, hold on to an array of high-end enterprises to settle down, 12 enterprises has signed a contract formally at present. The major projects include large data center construction project, the sapphire crystal construction project, education informationize platform and production base project, equipment  UAV rotorcraft industry project，sangu medical robots project, photochemistry engineering center construction project, sustained release tablet production and development base project.
