摘　　要：吉林省黑土面积占全国黑土覆盖总面积的15%,虽然开发较晚,但由于荒地的过度开垦、水土流失和培肥地力不当的原因,导致黑土退化严重。因此,要加大黑土保护的力度,建立保护性耕作制度,实施培肥地力工程,切实肩负起保护黑土的职责。The area 0f black soil in Jilin Province accounts for 15% of the total area covered by black soil in China.Although development is relatively late, black soil has been seriously degraded due to excessive reclamation ofwasteland, soil erosion, and poor raising of fertility. Therefore, we must strengthen the protection of black soil, estab-lish a protective farming system, implement fertility raising projects, and earnestly shoulder the responsibility of pro-tecting the black soil.
