Evaluation of Cultivated Land Fertility on Beer Barley Seed Farm of Gansu Province
摘要
Abstract
Taking beer barley seed farm of Gansu Province as the research area,overlay method between soil map and land use map were adopted to produce evaluation units,evaluation factors were chosen by Delphi approach and cluster analysis with their weights determined by AHP method.Finally the grades of cultivated land fertility were evaluated by fuzzy discrimination method.According to the integrated fertility index of all the evaluate units,cultivated land fertility on beer barley seed farm of Gansu Province was classified into five grades.The area and percentage of the first,second,third,fourth and fifth grade were 11.35 hm2（1.88%）,192.27 hm2（31.88%）,205.05 hm2（34.00%） and 194.42 hm2（32.24%）,respectively.The soil nutrient status was primarily evaluated according to the classification criterion of soil nutrient of Gansu Province.The results showed that soil nutrients content on beer barley seed farm of Gansu Province was lower in general.关键词
