摘要
一、自然概况黄土高原位于我国西北部,西起青海日月山,东抵山西太行山,北至晋陕长城,南达甘陕秦岭,构成一个独具特色的、比较完整的自然区域,其地理范围大致是北纬34°—41°,东经103°—113°之间。
TOPSIS method is used in the comprehensive analysis and evaluation of 11 grassland types in hilly regions of Loess plateau. This method is the most effective one among multi-objective optimization methods. Its basic ideology is to employ 'ideal solution' and 'negative ideal solution' in a multi-objective decision to make ordinations. It's proved that this method is not only simple and easy to grasp, but also can cxtend the application scope and improve the precision of comprehensive evaluation.
