Research Of Land Ecology And Environment In Ningxia Ningdong Energy & Chemical Industry Base

The author choose Ningxia Ningdong Energy & Chemical Industry Base as research region,use remote sensing and geography information system technique,contrast the land use structure and degree of Ningdong base since 2000. The mine eco-environmen of important mine also be researched. The author also found cause and trend of present situation layout of base,put forward measure of land use and ecology harness of NingDong base,gain the following fruition:1. contrast and research land use change by use satellite image date of 2000? 2007 and 2010, judge the land use degree, the author think the land use development degree is low.2. use the way of landscape ecology index,research land use structure characteristic of important region,clarified pressure and harmness of ecology.By analyse,the influence of mine development is faint to landscape, the landscape is even,the ecology is stable.3. By analyse the harmness of mineral extract? process, researched the soil erosion and surface subsidence of important region, the author think the transfer station and solid scrap are the main ecology harmness reason of the important region.4.by the above research conclusion,the author put forward countermeasure and proposal to the mine land ecology management and harness, it provide policy decision basis for management department to repair the mine environment.
