【 摘 要 】

Nowadays, green development has become an important concept of economic and social development. Ecological security issues have gradually been the concern of the general public in the rapid economic development. Based on the statistical data and remote sensing of Liaoning Province as the main data source, this paper extracts three groups of 12 indicators according to the principle of establishing the ecological security evaluation index, and the practical circumstance and data of the study district based on remote sensing technology. The weight is determined by the analytic hierarchy process and the entropy method. Using the comprehensive index method carries out land ecological security evaluation in Liaoning Province from 1000m∗1000m grid and the municipal administrative of evaluation unit. The result shows that the level of land ecological security is mainly medium-security and medium-high-security, and the middle part is gradually reducing to the east and west in Liaoning Province. The conclusion of this study is in line with the actual situation, which can provide the theoretical basis and valuable experience for the ecological construction of Liaoning Province.
