以宏观调控和微观监测的方式研究了环渤海盐碱荒地建立草畜系统后土壤理化性状、生物化学性状的演变规律及调控机理。结果表明，环渤海盐碱荒地经过工程治理、翻压二季田菁建立草畜系统5～7年后，土壤肥力指标达到当地四至二类耕地水平。
The evolution and regulation mechanism of soil physical and chemical properties and biochemical properties after the establishment of grass and livestock system in the saline-alkali-wasteland of the Bohai Sea were studied by macro-control and micro-monitoring. The results showed that the soil fertility index reached the level of four to two kinds of arable land in the Bohai Rim after the construction management of the saline-alkali wasteland in the Bohai Sea.
