This paper took eighteen villages, located in Shizhi town of Chongqing, as the examples and constructed an evaluation index system to assess land ecological security of the town by employing comprehensive analysis method based on the data of 2011, and explored the importance of its influencing factors of land ecological security, and then provided suggestions for future development of land ecological security in Shizhi town. The results showed that: (1) the land ecological security in Shizhi town was at a low level in general, but the diversity of land ecological security still existed among eighteen villages: one village was in a good state, thirteen villages were at a tipping state, while the other four villages were at a sensitive state; (2) the land ecological security viewed from spatial distribution was decreasing from middle to northwest and southeast; (3) the importance of influencing factors of land ecological security in Shizhi town had an obvious difference. Topographic condition was the most important, land use situation and land quality security were less important, while land carring capacity was the least important, and each village had obvious spatial difference of each influencing factor; (4) the whole town could be divided into four functional zones, which were urban ecological zone, modern fruit growing zone, ecological protection zone and agricultural ecological zone.
