草地资源监测样地布设方法探讨--以承德御道口牧场管理区为例

Discussion on layout method of grassland resource monitoring sample plot:taking Chengde Yudaokou Pasture Management Area as an example

草地资源监测工作有助于及时掌握草地资源的动态变化,为政府决策和制定草地修复方案和保护措施提供依据,以实际工作过程中积累的相关经验为基础,对草地资源监测工作中样地数量的确定以及样地布设方式进行了归纳总结;以御道口牧场草地资源监测为实例进行了相关方法的应用,结果表明:采用简单随机抽样法进行样地数量测算的监测区更适合以机械均匀布点法进行样地的布设;采用典型抽样法进行样地数量测算的监测区则以典型随机布点法或线路调查布点法进行样地布设更能体现其优势性。

The grassland resources monitoring helps to grasp the dynamic change of grassland resources in time,and provide evidence for the government decision-making,the grassland restoration plan and protection measures.Taking the practical experience in the process as the foundation,and taking the monitoring of grassland resources in Yudaokou pasture as an example,the layout method of grassland resource monitoring sample plot was summarized.The results showed that the monitoring area using simple random sampling method to calculate the number of sample plots was more suitable for the distribution of sample plots by mechanical uniform point method;and in the monitoring area where typical sampling method is used to calculate the number of sample plots,typical random method or line survey method is more advantageous.
