摘要
草原是国家陆地生态系统的重要载体,草原监测工作是促进草原生态文明建设的重要基础。本文在对黑龙江省草原资源全面掌握的基础上,分析了草原类、草原型、植物类型、生产力、综合植被盖度等指标,对黑龙江省草原的分布格局和生态状况进行全面的总结。结果表明,黑龙江草原自然灾害及病虫害发生的频度和危害程度程度总体呈下降趋势,监测与治理体系建设虽取得一定的成效,但仍存在不足。针对其不足,提出相关建议,以期为我国草原监测和防治提供参考。
Grassland is an important carrier of the national terrestrial ecosystem,and grassland monitoring is an important foundation for promoting grassland ecological civilization construction.In this paper,based on an overall understanding of the grassland resources in Heilongjiang Province,a comprehensive summary was made on the distribution pattern and ecological condition of grassland in the province with an analysis on such indicators as grassland category,grassland type,plant species,productivity and comprehensive vegetation coverage.The results showed that the frequency and severity of natural disasters,diseases and pests in grassland of the province have generally shown a downward trend and achievements have been made in developing the monitoring and management system.Deficiencies still existed and targeted suggestions were put forward to provide reference for monitoring and managing grassland in China.
