【摘要】：近年來,大規(guī)模的光伏電站建設(shè)帶來了一系列問題,環(huán)境影響就是最主要的一個(gè)方面。為了闡明光伏電站建設(shè)對(duì)土壤理化性質(zhì)、植被群落、小氣候的影響,本研究在靖邊縣陜西太陽能光伏發(fā)電有限公司內(nèi)布設(shè)光伏板未遮陰、遮陰和電站周邊3種類型樣地,45個(gè)土壤、植被調(diào)查樣方,通過外業(yè)調(diào)查和室內(nèi)分析研究了光伏電站建設(shè)對(duì)土壤理化性質(zhì)、植被群落種類、物種多樣性、生物量和小氣候的影響,同時(shí)對(duì)政府能源主管部門和光伏電站企業(yè)提出了一些具體建議。主要結(jié)果如下:(1)光伏電站建設(shè)后,相對(duì)于電站周邊,電站內(nèi)表層土壤(0-20cm)含水量增加了30-34%,有機(jī)質(zhì)增加了2.32-4.65%,速效磷增加了25.76-46.97%,速效鉀增加了27.91-28.41%,pH降低了1.25-6.65%,電導(dǎo)率降低了34.24-60.82%,土壤容重變化不大;在電站內(nèi),相對(duì)于遮陰區(qū)域,未遮陰的土壤含水量、pH、電導(dǎo)率、速效磷、速效鉀含量均增加,容重降低。(2)光伏電站建設(shè)后,相對(duì)于電站周邊,電站內(nèi)植物種類增加了129-143%,Shannon-Wiener指數(shù)增加了60.24-67.82%,Pielou指數(shù)增加了12.41-15.33%,Simpson指數(shù)增加了31.56-37.04%,生物量增加了127-144%。電站內(nèi)相對(duì)于遮陰區(qū)域,未遮陰的植物種類、Shannon-Wiener、Pielou、Simpson指數(shù)、生物量均增加。(3)光伏電站建設(shè)后,相對(duì)于電站周邊,電站內(nèi)風(fēng)速降低了23-43%,溫度降低了26-32%,空氣濕度增加了34-39%。(4)光伏電站建設(shè)能提高土壤肥力、降低土壤pH和全鹽含量,增加植物種類、物種多樣性和生物量�？偟膩砜垂夥娬窘ㄔO(shè)對(duì)土壤、植被有促進(jìn)作用。
[Abstract]:In recent years, a large number of photovoltaic power plant construction has brought a series of problems, the environmental impact is the most important aspect. In order to clarify the influence of the construction of photovoltaic power plants on the soil physicochemical properties, vegetation and climate, 3 types of samples of this study in Jingbian County of Shaanxi Power Generation Co. Ltd. in the layout of solar photovoltaic photovoltaic panels without shading, shading and power plants around 45, soil and vegetation plots, through field investigation and indoor analysis the construction of photovoltaic power plants affected the chemical properties, vegetation type, species diversity, biomass and climate on soil at the same time, some suggestions for the government departments in charge of energy and photovoltaic power station is put forward. The main results are as follows: (1) the construction of photovoltaic power plants, power plants around the power plant with respect, surface soil (0-20cm) moisture content increased 30-34%, organic matter, available phosphorus increased 2.32-4.65%, increased 25.76-46.97%, available potassium increased 27.91-28.41%, pH decreased 1.25-6.65%, the conductivity decreased 34.24-60.82%, the soil bulk density had little change in the power plant; in the shade, relative to the area, no shade of soil moisture, pH, conductivity, available phosphorus, available potassium content increased, bulk density decreased. (2) after the construction of photovoltaic power plants, plant species increased by 129-143%, Shannon-Wiener index increased by 60.24-67.82%, Pielou index increased by 12.41-15.33%, Simpson index increased by 31.56-37.04%, biomass increased 127-144%. The plant relative to the shade area, no shade plant species, Shannon-Wiener, Pielou, Simpson index and biomass were increased. (3) after the construction of the photovoltaic power station, the wind speed in the power station is reduced by 23-43%, the temperature is reduced by 26-32%, and the humidity of the air is increased by 34-39%. (4) the construction of photovoltaic power plant can improve soil fertility, reduce soil pH and total salt content, increase plant species, species diversity and biomass. On the whole, the construction of photovoltaic power station can promote the soil and vegetation.
