LAND POTENTIAL PRODUCTIVITY ASSESSMENT FOR ANNUAL AGRICULTURAL CROPS DEVELOPMENT IN QUANG XUONG DISTRICT BY APPLYING MULTI-CRITERIA EVALUATION AND GIS

Tóm tắt

The assessment of land potential productivity for agricultural production and land suitability for selected annual crops was based on FAO guidelines for land evaluation which were adopted and slightly modified for compatibility with Vietnamese conditions. A combination of three main factors consisting of ten variables of all related data were stored, analyzed, mapped and presented in ArcGIS software. Weighted Linear Combination Method developed by Hopkins and GIS techniques were used to analyze and determine the land potential for agricultural use in the study area. The results show that 5.26%, 83.10%, 10.06%, and 1.57% of the investigated areas were assessed as high potential, moderate potential, low potential and very low potential, respectively for growing crops. The findings from this study were also useful to support the land users and land managers to exploit agricultural land effectively.
