Abstract: [Objective] The aim of this study was to provide valuable information for solving the issues concerning agriculture, countryside and farmers, and to protect natural environment as well as promote the construction and development of ecological civilization. [Method] Based on the landscape ecology principle, the research used Google earth image datas to combine changes of the plaques from satellite in Hanyuan county known as "Flowers and Fruit Orchard Garden", to estimated the plant diversity, the change of landscape pattern and the value of ecosystem services. [Results] Results showed that the "Flowers and Fruit Orchards" were totally 91 pieces of plaques, about 152.5hm² since orchard established in 2009. The Landscape fragmentation index was 0.57, the Shannon diversity, evenness index, and landscape dominance index were 1.18 and 0.74 and 0.42, respectively. The total number of patches mutate were 113 and 170, covering 179.2hm², 222.1hm² in 2012 and 2015, respectively. The landscape pattern of variation were 0.62 and 0.73. Ecosystem service value in the study area showed a significant growth trend, with a striking development in tourism, which occupies more than 90 percents, increasing from ￥ 512 100 in 2009 to ￥ 2 468 700 in 2015, followed by the carbon sequestration and oxygen generation, then the water conservation, water and soil conservation, and last the windbreak and sand-fixation. Economic output of the fruit trees increased from ￥ 3 036 000 in 2009 to ￥ 33 033 000 in 2015. [Conclusion] The results suggest that it should develop the modern agriculture through taking advantage of natural resources on the condition that ecological security is maintained. It can not only protect ecological environment but also beneficial to solve the "agriculture, countryside and farmers" issues. Therefore, the experience of "Flowers and Fruit Orchard Garden" can be applied to other areas.
