补充资料：地价评估趋势评估法
地价评估趋势评估法
【地价评估趋势评估法】土地价格在一定的时间内由于受诸多因素影响，呈周期性的波动，但总趋势是上升的，因此，利用一定的数学模型，就可以求算出地价，一般要通过回归分析，找出土地价格与时间变量之间的函数关系，画出地价发展变化趋势图形，然后建立数学模型，进而推算出地价。若以Y代表历年地价，X代表时间，丫代表地价，其关系式为:y‘=a+bx(a、b为常数)。采用这一方法，需以长年积累起来的地价变动资料作为分析依据。地价的时间序列最好在ro年以上。因为时间序列愈长，愈能排除偶然因素和短期因素对趋势值的异常干扰。另外，用地价长期趋势图可比较两个地段地价_L涨的强弱程度，如果长期趋线越陡，则表明该地段地价升值性越强;反之，则表明该地价的升值性越弱。
