2020年东北黑土区30 m分辨率盐碱裸地分布数据集

本数据包括东北黑土区30m分辨率盐碱裸地分布数据集，反应东北黑土区盐碱裸地分布情况，为黑土地保护、土壤修复、土地规划等方面提供数据支撑。黑土地是大自然赋予人类的宝贵资源，东北黑土区已成为我国粮食生产的“稳定器”和“压舱石”，通过掌握东北黑土区盐碱裸地分布情况，为“用好养好”黑土地提供数据支撑。可广泛服务于黑土地保护、生态监测等相关学科的科学研究工作者。

This dataset is a 30-meter resolution saline-alkali bare land distribution dataset covering the Northeast Black Soil Region, which accurately reflects the spatial distribution of saline-alkali bare land in this area. It provides reliable data support for black soil conservation, soil remediation, land planning and other relevant fields. Black soil is a precious natural resource bestowed upon humanity, and the Northeast Black Soil Region has emerged as a "stabilizer" and "ballast stone" for China's grain production. By clarifying the distribution of saline-alkali bare land in the Northeast Black Soil Region, this dataset offers data backing for the initiative of "properly utilizing and nurturing" black soils. It can extensively cater to scientific researchers across relevant disciplines including black soil conservation and ecological monitoring.
