对黄平县耕地早熟马铃薯的适应性评价

利用ArcGIS9.0软件与县域耕地资源管理系统（3.2版）相结合,对黄平县耕地进行早熟马铃薯适宜性评价。结果表明：黄平县耕地高度适宜种植早熟马铃薯的面积为12 089 hm^2,占总耕地面积的27.39%;适宜种植早熟马铃薯的面积为26 418 hm^2,占总耕地面积的59.68%;勉强适宜种植早熟马铃薯的面积为5 343 hm^2,占总耕地面积的12.11%;不适宜种植早熟马铃薯的面积为284 hm^2,占总耕地面积的0.64%。由此可以看出,黄平县大部分耕地适宜早熟马铃薯生长。

Evaluation on Suitability of Huangping Arable Land to the Early Potato

In order to evaluate adaptability of Huangping arable land to the early potato,a combination strategy of ArcGIS9.0 software and management system of Huangping arable land resources is used in the present work.The evaluation result showed that the arable land area which is highly suitable for early potato planting is around 12089hm^2,accounting for 27.39% of the total,and that is moderately suitability for this crop is 26418hm^2,accounting for 59.68% of the total.However,the sub-suitable or unsuitable area are 5343 or 284hm^2,respectively,which accounts for 12.11%,or 0.64% of the total,respectively.These suggests that most of Huangping arable land is suitability for Oearly potato growth.
