吉林省西部与内蒙古东部农牧交错区草地退化现状及管理对策

Current situation of grassland degradation and its management options in farming-pasturing ecotone in western Jilin Province and eastern Inner Mongolia

吉林西部和内蒙古东部的农牧交错区是半湿润与半干旱气候的过渡地带,草地退化严重,主要表现为盐碱化和沙化。人为因素是导致草地退化的主要因素,人口压力和不合理利用是加速草地退化的主导因素。提出了要对现有草地开展健康诊断,对健康草地实施保护,对已受损的草地实施恢复与重建,建立科学管理制度等解决对策。

The farming-pasturing ecotone in western Jilin Province and eastern Inner Mongolia is a transitional area of sub-humid and semi-arid climate, where natural grassland was severely degraded and showed saline-alkalization and desertification. Anthropogcnic activity was the main cause of the grassland degradation, and larger population pressure and irrational land use were the dominant factors that accelerated this degradation. The management options for the degradation would be the carrying-out of ecosystem health diagnosis, protection of health grassland, restoration and reconstruction of damaged grassland, and establishment of scientific management system.
