【摘要】 我国高度重视盐碱地治理和农业高效利用。通过梳理分析现有盐碱地资源相关资料发现，我国盐碱耕地面积呈增长趋势，而优质可垦资源呈减少趋势，但盐碱地的数量、分布、质量等缺乏更加精准、全面的数据，底数不清问题突出。建议结合第三次全国土壤普查尽快摸清盐碱地“家底”，构建盐碱地资源合理利用长效机制，转变治理观念，推进以种适地，从而促进盐碱地有序开发和综合利用。更多还原

【Abstract】 Great attention has been paid to the reclamation and agricultural utilization of saline-alkali land in China.According to the available information about saline-alkaline land resources, the amount of salt-affected farmland increased while the superior salt-affected wasteland resources for reclamation decreased. However, the available data and information were too old and rough to guide the utilization of saline-alkali land at present. As a part of the third nationwide soil condition census, the general investigation is highly suggested for the systematic and sustainable management of saline-alkali land, with the emphasis on breeding saline-alkali tolerant crops and varieties.更多还原
