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。
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.
