摘要

准确地估测草地产草量

为确定合理载畜量提供重要的科学依据

对维护草原生态平衡

合理安排畜牧业生产等具有重要的理论与现实意义。估算草地产草量的手段可分为野外测量法、气象模拟模型法和遥感模型法三大类。利用大量的野外实际调查资料

应用微积分原理

推导出估算草地产草量的数学模型

并与其它模型进行对比

探讨了该方法的可靠性及估算精度。最后

将模型推广应用于生产实践中以估测牧草产量。

Abstract

Accurate estimation of reaso nable grassland yield is an important scientific basis in determining the carrying capacity .To maintain ecological balance of grassland

a reasonable arrangement of animal husbandry has important theoretical and practical significances .There are three main approaches to estimate grass production:field measurement

meteoro-simulation model

and remote sensing .A large number of survey data are used to construct a mathematical model.The model is used to estimate grass production and then compared with other models for its reliability and accuracy .At last

the modelis applied to estimating forage production
