%X Land resources in northwest Yunnan take highland and plateau as the leading factor where both altitude and latitute is the highest in Yunnan Province.Of the land resources,steep sloping land predominates over flat land;land in high cold horizon over land in low hot horizon;vertical differentiation is distinctive with outstanding horizontal differentiation;natural conditions are poor in most part of the region where socio economic development has lagged behind,hence it is difficult to exploit and utilize land resources.Sharp decrease in forest area,degradation of pastureland,and serious soil and water loss resulting from increasingly serious steep slope reclamation and rotational and abandoned planting due to population growth and economic development.Consequently,contradiction of population land environment became even sharper,causing more people poverty stricken and part of population losing survival conditions.Confronting the issues on biological resources conservation and promotion of socio economic development,efforts should be made to develop concept of sustainable utilization of land resources from the view point of mutual survival and coexistence of population land environment;to adjust land use structure by adopting measures suitable to local conditions;to strengthen infrastructure construction and improve land exploitation conditions;to increase intensive management level of land by relying on advancement in science and technology;to practice land arrangement by tapping new sources of supply and reduce consumption;to enforce land administration and supervision by means of legal procedures;and regulate land requirement by controlling population increase.
