基于GIS的唐山市及周边地区矿山环境遥感调查及动态监测

The investigation and dynamic supervision with remote sensing technique to the mine's geological environment in tongshan and surrounding region,gis based

以2006年的SPOT-5卫星影像及2000年航空图像为主要信息源,以遥感及GIS为技术支撑,对唐山市及周边地区矿山环境进行了调查与监测,结合野外实地查证,反映唐山市及周边地区矿业开发造成的环境污染十分严重。矿山环境破坏最严重的地方,主要分布在唐山市及滦县两大煤矿、铁矿集区。矿产采掘导致大量的固体废弃物占压耕地,并造成了大量的植被和耕地破坏及较严重的粉尘污染和水体污染,唐山市区局部出现了明显的地面沉降和塌陷。从2000-2006年,唐山市及周边地区矿山环境破环呈快速上升态势。

Taking the SPOT-5 at 2006 and aerial images at 2000 as main datum resources, supported by Remote Sensing technology and GIS techniques, the miners geological environment in tongshan and surrounding region was investigated and supervised. The result that was verified in field shows that, the mine＇s environmental pollution of tongshan and surrounding region is very serious, the worst in which mine＇s environment was destroyed, are Tangshan city and Luanxian county, which are abundant with iron, coal and nonmetal ores. Mine exploitation produced lots of solid offals that took up large cultivated land, destroyed mass of vegetation and land, bringed bad power-dust pollution and water-body pollution, came forth obvious ground-sinks or subsides in part of Tangshan city. From 2000 to 2006, the damages of mine＇s environment inTangshan city assumed a fast ascending situation.
