The Application of GIS in Analysis of Gross Agricultural Production: A Case Study of Hainan Island, China

To explore the distribution of gross agricultural production (GPA) is significant to the sustainable development of tropical agricultural growth. Taking Hainan Island as the study area, the spatial distribution and influence factors of GPA were elucidated by applying the GIS spatial analysis tools and factor analysis. The results showed that the distribution of Hainan GAP was uneven. The uneven distribution of GAP in counties was mainly caused by the variation of agricultural structure. The GPA was mainly determined by SAV, NEPA, and SAG. The distribution characters of Factor 1 was similar with the distribution of GAP in study area, and some agricultural planning can be made to improve the GAP of middle Hainan area, ie, increasing the sown area of vegetables and labor force input.
