【摘要】：本文基于專(zhuān)欄論文的全部研究結(jié)果,對(duì)墑情診斷模型進(jìn)行了理論分析、綜合評(píng)價(jià)和展望,目的是建立更實(shí)用的墑情診斷模型。研究結(jié)果如下:(1)87個(gè)墑情監(jiān)測(cè)點(diǎn)的降水量數(shù)據(jù)可以用就近氣象站的降水量代替;(2)分別就87個(gè)墑情監(jiān)測(cè)點(diǎn)所建立的6個(gè)獨(dú)立模型和1個(gè)綜合模型(分時(shí)段診斷和逐日診斷2類(lèi))的診斷合格率都達(dá)到75%以上;(3)綜合模型優(yōu)于6個(gè)獨(dú)立模型的單獨(dú)使用;(4)所有模型和參數(shù)都是按監(jiān)測(cè)點(diǎn)建立和確定的,不存在下墊面因素的影響;(5)所有模型簡(jiǎn)單、使用3個(gè)獨(dú)立變量(前期土壤含水量、時(shí)段降水量之和和2次監(jiān)測(cè)之間的天數(shù))、參數(shù)容易獲得,只要有系列性的土壤含水量監(jiān)測(cè)數(shù)據(jù)和對(duì)應(yīng)的降水量(監(jiān)測(cè)點(diǎn)降水量或就近氣象站降水量)數(shù)據(jù)就可建模。
[Abstract]:Based on all the research results of the column paper, this paper makes a theoretical analysis, comprehensive evaluation and prospect of the moisture diagnosis model. The purpose of this paper is to establish a more practical diagnosis model of soil moisture. The results are as follows: 1) the precipitation data of 87 soil moisture monitoring points can be replaced by the precipitation of nearby weather stations.) six independent models and one comprehensive model for 87 soil moisture monitoring points have been established respectively. The qualified rate of diagnosis is more than 75%.) the integrated model is superior to the 6 independent models. (4) all the models and parameters are established and determined according to the monitoring points. All the models are simple, using three independent variables (soil moisture content in the previous period, the sum of precipitation in the period and the number of days between the two monitoring periods), and the parameters are easy to be obtained. As long as there are a series of soil moisture monitoring data and corresponding precipitation data (precipitation at monitoring point or nearby weather station) data can be modeled.
