彈簧曲線-
The study investigated aboveground growths of caragana korshinskii and artemisia ordosica planted in four modes, revealing that in different planting modes their densities, heights and canopy width and biomasses remained unchanged or tended to decrease slightly ; the young shoots of a. ordosica annually grew in a s - shaped cure and the young shoots of c. korshinskii grew fast in spring and grew slowly or cease to grow from july on ; the biomasses and leaf area indexes of c. korshinskii and a. ordosica annually varied in a double peak curve and there were 8 annual plants that invaded in the four planting modes and formed higher coverage ; the quadrat with only a. ordoska appeared to have obviously lower coverage and biomass that the other three quadrats
摘要對騰格里沙漠東南緣2種人工植被檸條和油篙在4種配置方式下地上部分的生長動態進行了研究，結果表明：不同配置方式下它們的密度、高度、冠幅和生物量基本不變或略微呈下降趨勢；油篙新梢的年生長動態呈s型曲線，檸條新梢春季生長速度較快， 7月份以後生長速度緩慢或基本停止生長；檸條、油篙地上生物量和葉面積指數的年變化均表現為雙峰型， 4種配置方式下共有8種1年生植物人侵，並具有較高的植被蓋度；同其它3個樣地相比，純油篙樣地1年生植物的密度、蓋度和生物量明顯偏低。 -
The paper concludes that the changing rate of ndvi of rain forest in tropic is the smallest, the changing curve is smooth, while the changing rate of ndvi of the deciduous broad leaf forest in warm - temperate zone is the largest the change of ndvi is the most conspicuous in winter and spring ( especially in april ) while is not conspicuous in summer and autumn by analyzing the change of ndvi along latitude using the ndvi value of different vegetation types along the same longitude. the vegetation index from warm temperate zone to semitropical zone has obvious transition, while other areas have no distinct change by analyzing the change of ndvi from temperate zone to semitropical zone to tropical zone using ndvi averagejn the same time it is concluded that the sink value in the beginning of the year 1995 is from the influence of the monsoon in east of china by analyzing the ndvi curve of several typical needle leaf forests. the relation between ndvi value and temperature is conspicuous while the relation of precipitation is less or not by analyzing the relation between ndvi and temperature and precipitation finally it can get the conclusion that the change of river area is the smallest, the change of sienna area is the greatest by analyzing two phases of tm data in 1987 and 1997 with rs technic
利用從同一經度的不同森林類型ndvi值分析，沿緯度方向ndvi變化可得出， ndvi在冬春季變化最明顯（尤其是在4月份最大） ，而在夏季和秋季變化不明顯。利用ndvi均值進行分析，從暖溫帶到亞熱帶到熱帶的變化情況發現，從暖溫帶到亞熱帶ndvi指數形成明顯的階躍，而其它區域沒有太大的變化，同時對幾種典型的針葉林曲線分析可知其年初的凹值源自於我國東部季風的影響。利用ndvi數據分析其與月均溫度與降水的相關性得出與溫度相關性較為顯著，而與降水相關性不顯著或無相關性。 -

After analyzing, the author got the basic character of tidal flat hydrodynamic : the time of flooding on bare flat and ebbing is basically the same and the time of flooding on pioneer zone of salt marsh is a little short ; the process curve of current speed on bare flat did not appear peak value on the beginning of flooding and at the end of ebbing but presented double peak, that is, it presented double peak in winter and spring and ebbing peak value disappeared in summer and autumn, salt marsh presented single peak character in a year and the process curve in tidal creek presented double peak ; all current direction on every spot presented gyration current and the current speed changed rapidly during the high water level without obvious slack water period
分析得到了潮灘水動力基本特徵：光灘水位漲潮和落潮時間基本相等，而鹽沼前緣帶水位漲潮時間略短；光灘流速過程線在漲潮初和落潮末出現峰值，呈現「雙峰型」特徵，鹽沼前緣帶則冬、春季節呈現「雙峰型」 ，夏、秋季節落潮峰值消失，鹽沼帶四季呈現單峰特徵，潮溝內過程線為「雙峰型」 ；各測點流向均呈現回轉流特徵，在高水位時流向迅速改變，不存在明顯的憩流。 -
