In the end, cluster - analysis - based floating control historical regression method with uniform precipitation and atmospheric precipitable water as metoorological covariates could more validly evaluate efficiency of cloud seeding operations and significant level of ca - fcm method was higher than the other methods, because it adopted cluster analysis which highly improved the correlativity between rainfall distributions in the control area and target area, and used grid interpolation which enhanced exactness of calculating precipitation rainfall, and chose atmospheric precipitable water as the covariant which increased the inferential accuracy of natural rainfall on the cloud seeding operational area
最後，得到以降水量和整層大氣可降水量為協變量的ca - fcm方法，由於採用聚類分析（ ca ）方法，提高了對比區和影響區相關性；採用網格插值技術提高了雨量的計算準確度；引入了不受催化影響的物理協變量（整層大氣可降水量） ，提高了作業區自然降水量估計值的準確性；所以評估效果最好，顯著水平高於0 . 05 。 -
