The Highgroundwater Area Of Coal Village Migrationin Occupies Fillingbalance By The Theoretical Model And Application

As we all known,In the eastern of China,the land resources and coal resources in high ground-water level plain areas are very important, In these area,coal resources and arable land and villagesare high degree of coincidence, which formed the coal grain complex area and coal mining undervillage area.In the high ground-water level mining, coal mining caused the surface subsidence thatresult in groundwater out, a large number of cultivated land submerged, food production declineor even no kernels or seeds are gathered, Lots of farmland lost the capacity of grain production,Due to the plain area population density higher, the village higher concentrated, land reserveresources reducing, making the contradiction between people and land manifest. So, coal undervillage moving becoming the common problem of current government and coal enterprises, It alsothe focus of social concerning, and limited the sustainable development of mining city or area.The study based on many achievements which possessed by the land reclamation andecological reconstruction, According to the policy of arable land requisition-compensationbalance, designed a new model which dim the village migration in coal mining land as the center.According to the new theory about village migration in coal mining, First of all, we have a detailedanalysis to the factors which influence land requisition and compensation. Next, Constructed land control model which based on coal under villages PSO relocation.And based on the "AHP-CA"build the coal mining under village site layout model. Finally, In this study, take the Shandongmining area as an example, designed the village migration optimization scheme. The resultsshowed that the new theory can be used not only to meet the village migration in coal mining landdemand, but also to ensure the grain yield in the regional space not reducing, and Ultimately toachieve energy security, social security and food security and win-win situation.
