【摘要】：太平湖位于安徽省黃山市黃山區(qū)境內(nèi),是安徽省最大的水庫(kù)型湖泊。2012年,太平湖被列入國(guó)家第二批生態(tài)環(huán)境保護(hù)專項(xiàng),2014年被列入全國(guó)15個(gè)重點(diǎn)保護(hù)湖泊之一,其生態(tài)環(huán)境保護(hù)已成為今后工作的重中之重。目前,對(duì)太平湖生態(tài)本底調(diào)查的資料還很缺乏,對(duì)太平湖初級(jí)生產(chǎn)力的調(diào)查研究更是極少。本研究于2012年11月到2014年10月期間,對(duì)太平湖的初級(jí)生產(chǎn)力進(jìn)行了調(diào)查研究,初步了解了太平湖初級(jí)生產(chǎn)力的空間和時(shí)間分布,并對(duì)不同采樣點(diǎn)和不同時(shí)間所得的結(jié)果進(jìn)行方差分析。利用Pearson相關(guān)分析探討了初級(jí)生產(chǎn)力與環(huán)境因子(WT、葉綠素a)之間的相關(guān)性,利用初級(jí)生產(chǎn)力和葉綠素a濃度等指標(biāo)對(duì)太平湖水環(huán)境質(zhì)量進(jìn)行了初步的生態(tài)學(xué)評(píng)價(jià)。并通過(guò)與前人的研究結(jié)果進(jìn)行對(duì)比,分析了太平湖水生態(tài)環(huán)境演變趨勢(shì)。本文還通過(guò)與其他湖泊的初級(jí)生產(chǎn)力進(jìn)行比較,探討了太平湖的營(yíng)養(yǎng)水平和漁產(chǎn)潛力,以期為太平湖的水生態(tài)環(huán)境保護(hù)及漁業(yè)開(kāi)發(fā)生產(chǎn)提供基礎(chǔ)數(shù)據(jù)和參考資料。本論文所得的主要結(jié)果如下:1.調(diào)查期間,太平湖水柱毛初級(jí)生產(chǎn)力為4.65±4.17 g/(m2·d),變化范圍為0.52~18.94 g/(m2·d),最大值出現(xiàn)在2013年5月的H4,最小值出現(xiàn)在2013年9月的H3。水柱呼吸量為5.33±3.87 g/(m2·d),變化范圍為0.45~15.88g/(m2·d),最大值出現(xiàn)在2013年7月的H5,最小值出現(xiàn)在2014年10月的H1。水柱凈生產(chǎn)力為-0.68±4.36 g/(m2·d),變化范圍為-11.69~11.71 g/(m2·d),最大值出現(xiàn)在2013年9月的H5,最小值出現(xiàn)在2013年7月的H5。P/R系數(shù)1,調(diào)查期間太平湖處于自養(yǎng)狀態(tài)。2.時(shí)間分布上,調(diào)查期間,太平湖水柱毛初級(jí)生產(chǎn)力出現(xiàn)三個(gè)峰值,分別為2012年11月、2013年5月和2014年7月;2013年5月水柱毛初級(jí)生產(chǎn)力水平最高,達(dá)到了7.77±6.30 g/(m2·d)。水柱呼吸量的時(shí)間動(dòng)態(tài)分布與毛初級(jí)生產(chǎn)力相似,2013年7月和2014年7月為水柱呼吸量高峰期,2014年1月、4月、10月的水柱呼吸量較低。2013年水柱呼吸量高于2014年。太平湖各月水柱凈初級(jí)生產(chǎn)力分布,與水柱呼吸量相反,2013年7月和2014年7月,水柱凈初級(jí)生產(chǎn)力處于谷值,最低值為2013年7月,達(dá)到-5.57±4.70g/(m2·d),2013年3月和2013年9月,水柱凈初級(jí)生產(chǎn)力水平也較低,都為負(fù)值。3.水平分布上,太平湖水柱毛初級(jí)生產(chǎn)力的水平分布為H1、H2、H3相近,分別為3.20±1.66g/(m2·d)、3.58±2.59g/(m2·d)、2.98±2.35g/(m2·d);H4、H5相近,分別為7.61±6.61g/(m2·d)、6.06±3.72g/(m2·d)。H4、H5的水柱毛初級(jí)生產(chǎn)力顯著高于H1、H2和H3。水柱呼吸量呈現(xiàn)出與水柱毛初級(jí)生產(chǎn)力相似的水平分布規(guī)律,也是H4、H5顯著高于H1、H2、H5;H5的水柱呼吸量大于H4,這與水柱毛初級(jí)生產(chǎn)力的分布規(guī)律相反。除H4外,其余各點(diǎn)水柱凈初級(jí)生產(chǎn)力均為負(fù)值,其水平分布表現(xiàn)為H4H3H5H1H2。4.研究期間,太平湖葉綠素a濃度平均值為5.88±4.79 mg/m3。2012年11月-2013年5月之間葉綠素a濃度波動(dòng)較小,從7月開(kāi)始快速增加,9月達(dá)到峰值,濃度達(dá)到14.13 mg/m3。2014年,葉綠素a含量波動(dòng)情況與2013年相似,分別從2013年5月和2014年4月開(kāi)始葉綠素a含量大幅增加,增幅均超過(guò)了100%。水平分布上,葉綠素a濃度在上游和中游較高,尤其在最上游H1處,為最高,達(dá)到了9.99 mg/m3;H2、H3次之,下游H4、H5最低。這與透明度的水平分布相反,透明度的水平分布特征為H1(2.18m)H2、H3(分別為2.85m和2.95m)H4、H5(分別為3.87m和3.87m)。5.根據(jù)太平湖水柱毛初級(jí)生產(chǎn)力的值,評(píng)價(jià)太平湖為富營(yíng)養(yǎng)水體。以葉綠素a濃度為平均指標(biāo),太平湖為中營(yíng)養(yǎng)水體。結(jié)合太平湖的水質(zhì)和實(shí)際觀感,以及本課題做的有關(guān)浮游生物方面的研究,我認(rèn)為把太平湖評(píng)價(jià)為中營(yíng)養(yǎng)水體較為合適。按根據(jù)華中農(nóng)業(yè)大學(xué)水產(chǎn)系《實(shí)用水庫(kù)漁業(yè)技術(shù)》提供的公式計(jì)算測(cè)算,太平湖每年鰱、鳙魚(yú)產(chǎn)潛力為2012.8 Kg.6.調(diào)查期間,太平湖毛初級(jí)生產(chǎn)力的均值分別為4.65 g/(m2·d),與1992年的初級(jí)生產(chǎn)力2.67 g/(m2·d)相比,增長(zhǎng)了74.1%。
[Abstract]:Pinghu is located in the territory of Anhui province Huangshan City Mount Huangshan District, is the largest reservoir in Anhui Province Lake.2012, so Pinghu was included in the second batch of national environmental protection projects, 2014 was included in one of the 15 focus on the protection of lakes, the ecological and environmental protection has become a priority among priorities for future work. At present, investigation of Pinghu too the ecological background information is lack of investigation and Research on primary productivity in Pinghu is too little. This study from November 2012 to October 2014 period, primary productivity of Pinghu is investigated, a preliminary understanding of the Pinghu's primary productivity of the spatial and temporal distribution, and the different sampling points and different time results analysis of variance. Using Pearson correlation analysis on primary productivity and environmental factors (WT, chlorophyll a) the relationship between the primary productivity and chlorophyll a concentration The preliminary evaluation indexes of ecology of the Taiping Lake water environment quality. And through comparing with the previous research results, analyzed the evolution trend of Taiping Lake ecological environment. This paper also compares the primary productivity and other lakes, discusses the nutrition level and Pinghu's fishery potential, in order to Pinghu water ecosystem too the environmental protection and the development of fishery production and provide basic data and reference. The main results of this thesis are as follows: 1. the survey period, the Taiping Lake water column gross primary productivity was 4.65 + 4.17 g/ (M2 - D), the change range of 0.52~18.94 g/ (M2 d), the maximum value appeared at H4 in May 2013 and the minimum value appeared H3. in the water column respiration in September 2013 amounted to 5.33 + 3.87 g/ (M2 - D), the change range of 0.45~15.88g/ (M2 - D), the maximum value appeared at H5 in July 2013 and minimum in October 2014 H1. column net productivity is -0 .68 + 4.36 g/ (M2 - D), the change range of -11.69~11.71 g/ (M2 d), the maximum value appeared in the September 2013 H5, the minimum value appears in the H5.P/R coefficient in July 2013 1, during the investigation in Pinghu too autotrophic state.2. time distribution, during the investigation, the Taiping Lake Water column gross primary productivity appeared three peak as of November 2012, respectively, May 2013 and July 2014; May 2013 gross primary productivity of water level is the highest, reaching 7.77 + 6.30 g/ (M2 - D). The amount of time the water column respiration dynamic distribution similar to gross primary productivity, July 2013 and July 2014 for the water column respiration peak, in January 2014, April, October the volume of low water column respiration.2013 the water column respiration was higher than that in 2014. So each month in Pinghu water net primary productivity distribution, and water column respiration in July 2013 and July 2014, the net primary productivity of water in the valley, the minimum value is reached in July 2013 鍒，
