當今的城市中,綠色植物已經成為家居美化中必不可少的因素,隨著人們越來越崇尚「熱愛綠色、回歸自然」的生活方式,家庭園藝將會被更多的家庭所熱衷,粗通園藝的人都知道,用雨水、河水澆花遠勝于自來水,可是由於時間和居住條件所限,城市居民很難在下雨的時候收集足夠的雨水儲存起來用於家庭園藝,建議售賣園藝土等園藝用品的市場商戶,能在雨雪天收集大量的雨水、雪水儲存起來,賣給熱愛養花的家庭,價廉物美,一方面可解決公寓樓中中長期用自來水澆花帶來的不良問題,一方面給自己帶來些收益,最重要的是: 「涓涓細流,匯成江河」 ,如果這種設想能發展成長期的商業行為,並在各大城市都實行起來,那每年能節約多少自來水呀!By integrating the backmixing theory of reaction engineering with predictive model of river pollution in environmental quality assessment study, the predictively longitudinal dispersion model of river quality was got and analyzed
