| Abstract: |
| In protection plans of basic farmland，high-quality is paid attention while connectivity is ignored. This
paper analyzed the change of spatial connectivity of basic farmland in Luoding city，Guangdong province in 2010 and
2020 by using generate near table method and nearest neighbor analysis，respectively. The results showed that by both
the two methods，the spatial connectivity of basic farmland of Luoding city improved，and the spatial connectivity of high
quality basic farmland was obviously lower than the overall shape of basic farmland. The evaluation of spatial connectivity
of overall basic farmland ignored its quality，and affected the accuracy of the evaluation. High quality basic farmland’s
spatial connectivity better reflected the overall shape of basic farmland. At last，some suggestions for improving the spatial
connectivity level of basic farmland were put forword based on the comparison analysis of the two periods. |
