Using Rough Set and Fuzzy Method to Discover the Effects of Acid Rain on the Plant Growth

Today many living and non-living systems become harmed and damaged as a result of acid rain. Similarly, acid rain also affects our local plantation and crop growing. This paper applies rough set and fuzzy method to digging a little knowledge out from the raw data of acid rain. The theories in rough set can directly generalized knowledge form raw data by the methods of knowledge reduction. In other words, we can find out the production rule or decision rules by using the definition of the rough set; then, we apply an algorithm of fuzzy cover to draw some conclusions from the production rule of the effects of acid rain on the plant growth
