探讨了将透光率为5%、15%、25%的西畴青冈幼苗光照改为透光率40%的处理条件下，西畴青冈叶绿素含量及比值、净光合速率、叶绿素荧光参数fv/fm随时间的变化。结果表明：随光照强度增加，叶绿素a、叶绿素b、叶绿素a+b的含量降低，叶绿素a/b、类胡萝卜素含量、类胡萝卜素/a+b的值增加。净光合速率（Pn）和叶绿素荧光参数fv/fm先下降后上升。说明西畴青冈幼苗在光照增强的情况下,会通过减少叶绿素含量来减少对光的吸收，提高类胡萝卜素的含量以便于保护叶绿素和耗散多余的光能，净光合速率（Pn）和叶绿素荧光参数fv/fm的变化表明西畴青冈幼苗在光强增加时会受光抑制使净光合速率（Pn）降低，而随着处理时间的增强，净光合速率（Pn）会有一定恢复。在光强增加情况下，西畴青冈能进行自身的调节，以便于适应光环境变化。
希望用生态学的专业英语回答。
The Xi Chou county Qing Gang county young seedling illumination having discussed with transmitting rate for 5% , 15% , 25% switches over to be under transmitting rate 40%'s treatment condition , Xi Chou county Qing Gang county chlorophyll contents and ratio, close the rate , the chlorophyll fluorescence parameter fv/fm change with time nothing but only. Result is indicated: The intensity increases by , the chlorophyll a , chlorophyll b , chlorophyll a + b contents reduce with illumination, chlorophyll a/b , carotenoid contents , carotenoid/ a + b value increase by. Nothing but brightness closes the rate (Pn) with chlorophyll fluorescence parameter fv/fm rises after coming down first. Sorption that can cut down camera setting by cutting down a chlorophyll coming contents, improves the carotenoid contents to easy to protect a chlorophyll and to dissipate unnecessary optical energy , that nothing but brightness closes the rate (Pn) with chlorophyll fluorescence parameter fv/fm chan
