Temporal stability of throughfall pattern in areca plantation
Areca plantation, as a typical economic forest, is widely distributed in the tropical areas. Its unique canopy structure alters the spatial pattern of throughfall, which further influences the hydrogeological processes and results to different ecological effects, such as soil erosion.

However, available information is limited on how the areca plantation changes the spatial pattern and the temporal stability of throughfall. Here the spatiao-temporal variation of throughfall was observed under 33 rainfall events in areca plantation in Hainan Island. We found that throughfall changed significantly with locations under canopy of areca plantation(P<0.01). The throughfall rate was different near the trunk(85.6%), in the center of canopy(48.3%), and at the edge of canopy(59.8%). The location near the trunk had the highest throughfall. The throughfall rate in the east of the trunk was significantly higher than that in the south(P<0.1), indicating that wind also impacted the spatial pattern of throughfall. In addition, The throughfall of different locations under the canopy of areca plantation presented high variability over time(65.7%). However, the throughfall in the center of canopy was relatively stable over time(55.6%), while it had poor temporal stability near the trunk(25%) and at the edge of canopy(19.4%). Small differences(about 1/3) of temporal stability in throughfall among different directions were observed. The distance from the trunk and the rainfall were the main factors affecting the temporal stability of throughfall. Furthermore, the former influenced the temporal stability of throughfall mainly through leaf angle. The mean angles of leaves were negatively correlated with the temporal stability of throughfall(P<0.05). The temporal stability of throughfall was the weakest under moderate rainfall. With the increase of rainfall, the "wetting effect" of the canopy decreased, and the "drying effect" increased. The above results improved our understanding how tree species impact the temporal and spatial patterns of throughfall, which could also help to explain the spatio-temporal dynamics of soil moisture and soil erosion at small scale in plantation ecosystems.</description><identifier>ISSN: 1000-0933</identifier><identifier>DOI: 10.5846/stxb201803130491</identifier><language>chi ; eng</language><publisher>Beijing: Science Press</publisher><subject>Canopies ; Drying ; Ecological effects ; Environmental changes ; Geology ; Herbivores ; Hydrogeology ; Leaf angle ; Leaves ; Plantations ; Rainfall ; Soil dynamics ; Soil erosion ; Soil moisture ; Soils ; Stability ; Temporal variations ; Throughfall ; Tropical forests ; Wetting</subject><ispartof>Sheng tai xue bao, 2020-01, Vol.40 (6), p.1967</ispartof><rights>Copyright Science Press 2020</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27923,27924</link.rule.ids></links><search><creatorcontrib>Zhao, He</creatorcontrib><creatorcontrib>Wen, Zhi</creatorcontrib><creatorcontrib>Liu, Yanqiu</creatorcontrib><creatorcontrib>Zheng, Hua</creatorcontrib><creatorcontrib>Ouyang, Zhiyun</creatorcontrib><title>Temporal stability of throughfall pattern in areca plantation</title><title>Sheng tai xue bao</title><description>Areca plantation, as a typical economic forest, is widely distributed in the tropical areas.
