This paper aims to realize the targeted investigation of distribution area of potential scenic view-point in landscape planning,and a new quantitative evaluate and screen method is proposed.By using GIS and fuzzy analytic hierarchy process,the evaluation system of distribution area of potential scenic view-point was established,and the screening threshold value was provided by local investigation,and the case test was carried out in Jiulangshan mountain park.An evaluation system of Suitability of distribution of scenic view-point,including the suitability of distance between view-point and scene,suitability of view-able area size,residence suitability and traffic accessibility is constructed.The result shows that :after expert consultation and fuzzy analytic hierarchy process analysis,the importance degrees of suitability of distance between view-point and scene,suitability of view-able area size,residence suitability and the traffic accessibility are 0.331,0.323,0.161 and 0.185.Based on GIS and fuzzy analytic hierarchy process,the suitability evaluating of the distribution of scenic view-point in Jiulangshan mountain park was completed,and result shows that the evaluate value ranging from 0.02 to 0.74.According to the local investigation results,a total of 16 suitable view-point were identified.According to the value of the 16 scenic view-point in the previous evaluation,the minimum value,the first quartile,the mean value and the median value is 0.40,0.43,0.48±0.06,0.50.When the screening thresholds were set as 0.4,0.43,0.48 and 0.50,respectively,the distribution area of potential scenic view-point accounts for 16.9%,8.9%,3.6% and 2.3% of the total research area.The screening results were tested,and 80.0% of the points were within the appropriate range obtained by screening.The evaluating and screening of distribution area of potential scenic view-point are basically realized.
