Abstract：

This　paper　firstly　educed　some　necessary　formulae　such　as　incidence　angle　and　the　vector　of　reflected　sunlight　and　tracking　tilt-angle　via　vector　analysis.　Then,　shading　and　blocking　distribution　of　analyzed　mirror　element　was　got　by　coordinates　transform　and　ray-tracing　method　and　annual　average　shading　and　blocking　efficiency　of　LFR　mirror　field　was　analyzed　by　Statistic　means.　Finally,　the　effect　of　shading　and　blocking　efficiency　of　LFR　mirror　field　due　to　different　linear　absorber　high,　spacing　between　adjacent　mirror　element　and　width　of　mirror　slat　was　analyzed　and　fitted　calculating　model　of　shading　and　blocking　efficiency　of　LFR　mirror　field　was　presented.
