Abstract: Land use structural optimization is an effective approach to realize land sustainable utilization and allocate limited land resource rationally. Grey multiple objectives programming (GMOP) model based on China terrestrial ecosystem service value was constructed and applied to Lilin town. The result shows that GMOP model has more practical applicability and takes ecologic, social and comprehensive benefit into consideration. There are three programs after optimization. Program I is comprehensive improvement and constructing ecological economy type, program II is gross cultivated land dynamic balance type and program III is compromise type. There are still problems in programs II and III, such as distribution in disorder, land left unused or abandoned. Based on the benefits above, Program I>Program III> Program II. Program I is the optimal case. Its comprehensive benefit is 8.43208×107 RMB yuan/a.
