【目的】解决“三农”问题,保护自然环境和促进生态文明建设与发展。【方法】以景观生态学原理为基础,利用Google earth 卫片资料,结合四川省汉源县“花海果都”果园建园前后卫星影像斑块组成及其变化,对该区域植物多样性、景观格局变化及生态系统服务价值进行了估算。【结果】结果表明:“花海果都”果园自2009年建园前斑块总数为91块,面积为152.5 hm2,其景观格局指数中景观破碎化指数0.57、Shannon 多样性指数1.18、Piolou 均匀度指数0.74、景观优势度指数0.42;2012年、2015年斑块总数变异为113块、170块,面积分别为179.2、222.1 hm2,其景观格局变异为0.62及0.73,研究区生态系统服务价值显示出明显增长趋势,生态系统服务价值中旅游发展的效益最显著,占据90%以上,由2009年的51.21万元增至2015年的246.87万元。其他生态系统服务功能价值依次为固碳制氧、涵养水源、水土保持、防风固沙。研究区果树经济产出由2009年303.60万元增长至2015年的3303.30万元。【结论】目前在四川山区应在国家生态安全的前提下,通过发挥本地的自然资源优势,走现代农业之路。这样不仅可以达到保护生态环境,同时也解决了本地“三农”问题。因此,汉源花海果都的经验是值得肯定和推广的。
[Objective]The aim of this study was to provide valuable information for solving the is-sues 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 esti-mated 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 152.5 hm2 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 179.2 hm2 ,222.1 hm2 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 genera-tion,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 ap-plied to other areas.
