摘要
利用催化剂线源扩散模式确定人工增雨作业后的目标区 ,并采用非随机活动对比区和目标区分层历史回归的方法估算作业效果。为评估增雨对农业的影响 ,利用自然降水对农作物产量贡献的积分回归 ,获得降水对农作物贡献系数。建立了每次人工增雨对主要农作物的经济效益模型。从而可根据增雨量对农作物产生的直接经济效益进行实时、动态、定量评估。
The regression analysis method of non stochastic process and movable control over the target area was used to assess seeding effect.The target area was determinated by diffusion equation.For assessment effect of cloud seeding for agriculture,contribution coefficient of precipitation to crop production was obtained using integral regression of precipitation.An economic benefit model of main crop was established.It can be used to assess quantitative effect of cloud seeding.
