Based on the difference among those flora in guangdong province , the author draws a conclusion that the boundary between the “ middle subtropic “ and the “ southern subtropic “ in guangdong province begins at lianshan county ( 24 ? 20 “ n ) iv at west , and ends at dapu county ( 24 ? 30 “ n ) at east , and the boundary between the tropic and the “ southern subtropic “ begins at lianjiang county at west , pass yangjiang and then extend to the seaside of taishan 本文認為,廣東省植物區系內部差異支持以下結論:廣東省中亞熱帶和南亞熱帶的分界線西起連山縣的24 20 n ,東至大埔縣的24 30 n ,廣東省南亞熱帶與熱帶的分界線西起廉江,東至陽江,延伸至臺山沿海一線。據此結論,古兜山位于熱帶北緣緊鄰南亞熱帶。

The activity of cold air and interannual variation of low level jet are important cause of interannual variation of the rainfall in april . interannual variation of subtropic high is the main cause of interannual variation of the rainfall in may over north china . there is significant negative correlation between interdecadal variation of the rainfall in april and that of sst in the areas of equatorial indian ocean and tropic middle - east pacifi 華北4月降水與熱帶中東太平洋、赤道印度洋海溫年代際變化呈明顯的負相關:華北5月降水與熱帶中東太平洋、赤道印度洋海溫年代際變化存在明顯的正相關:熱帶海溫的年代際異常引起的副熱帶高壓的年代際異常可能是影響華北4 、 5月降水異常的重要原因。

As far as the relationship between gmnr flora and other flora outside of guangdong province , the analysis shows that gmnr is more similar to jianfengling than to lushan mountain an jiulong mountain . so , the author thinks gmnr is floristically a transitional zone from the tropic to subtropic , and it should be a part of east - asia region , belonging to the “ paleotropic kingdom “ 同時,與省外地區植物區系的比較結果表明,古兜山等廣東地區與與熱帶區系海南尖峰嶺植物區系的聯系比與中亞熱帶植物區系的廬山、九龍山植物區系的聯系要密切些(甚至強于與車八嶺植物區系的聯系) ,進一步證明了本植物區系熱帶向亞熱帶過渡的性質,為華南省植物區系的組成部分,隸屬于古熱帶植物區。

Based on analysis of fixed position climate observation and on - the - spot investigation in the east and west parts of subtropic mountainous areas in china , the laws of heat and water resources spacetime distribution were studied comparatively , the effects on agriculture layout were discussed 通過定位氣候觀測資料分析和實地考察,對中國亞熱帶東西部山區水分資源和熱量資源的時空分布規律進行了比較研究,并探討了水熱資源對農業生產空間布局的影響。

( 3 ) the polar eddy , the west circumfluence on 500hpa medium latitudinal region ands subtropic circumfluence are the key systems of tpnes floods precipitation and , the wet years have abundant vapor , moreover , the omga is positive in all atmosphere ( 3 )極渦、中高緯西風環流系統和副熱帶系統是影響青藏高原東北側區汛期降水的大尺度環流背景關鍵系統。同時,多雨年的主要流場特點是有利于水汽輸送,且整層大氣始終表現為上升運動。

The harmfulness caused by the low temperature in wintertime to the main tropic and south subtropic crop and fruit was discussed and summarized 討論和總結了冬季低溫給廣東主要熱帶南亞熱帶作物帶來的危害。
