4.5 Protect untouched arable land resources and reclaim orderly
Wasteland suitable for farming constitutes major untouched arable land resources. Withthe acceleratioof urbanizatioand industrializatioprocesses iChina and rapid progressithe infrastructure construction， it is necessary to substantially strengthethe protectioofwasteland suitable for farming and avoid destructive development. While maintaining the quan-tity of untouched arable land resources， more attentioshould be paid to the conservatioof theeco-environment around the untouched arable land （Che2001）. We should encourage andsupport farmers and flagship enterprises， under the preconditioof not degrading eco-environ-ment， to invest more ireclaiming the wasteland suitable for farming， increase input， built itinto stable and high yield cropland and incorporate it into the category of capital farmland forprotectioaccording to law.
Besides， with respect to the methods and priority for arable land protectioiChina， dif-ferent measures should also be adopted iline with the regional difference iland resources： As.the farmland is good iquality and high iyield ithe eastercoastal region， land consolidationshould be carried forward vigorously othe basis of more effective protectioof existing capitalfarmland iorder to improve agro-productioconditions， upgrade farmland quality and yieldand increase acreage; Through city land consolidation， intensive land use should be promotedand the pressure ing from use of farmland for non-agricultural purposes due to rapid devel-opment of regional economy and urbanizatiobe eased. At the same time the agricultural pro-ductiostructure should be optimized and othe prerequisite of not damaging the topsoil， labor-intensive productioand processing with advanced technology should be carried out to increasethe added value and petitiveness of farm produce.
The middle region， featured by a large quantity of arable land， ideal sunshine and tempera-ture and good land utilization， is the basis to ensure our nation's food security. But ithis re-gioa large part of farmland suffers from natural hazards including drought， flood and saliniza-tioand the medium- and low-yield land is distributed extensively. Therefore the emphasisshould be shifted from maintenance of acreage to yield. Except for key protectioof high-yieldfertile farmland， prehensive treatment of medium- and low-yield fields should be enhancedto buffer the harm of natural calamities and increase the overall productiocapacity of farmland（Tiaet a/. 2002） .
