Phenological observation data of plant communities from 1982 to 1996 at 5 sites and a method for phenological cumulative frequency modeling were used to determine the beginning dates of local phenological seasons and their corresponding threshold values of normalized difference vegetation index in each year.

利用1982～1996年5个站点的植物群落物候观测数据和物候累积频率拟合法，划分各站逐年的植被物候季节，并确定各季节初日对应的当地归一化差值植被指数阈值。

Namely, the first, the beginning, end and length of growing season of every type of vegetation is estimated with threshold method and moving average method, and the beginning end and length of growing season of vegetation from 1982 to 1999 is fitted linearly, finally, linear trend of the beginning end and length of growing season of vegetation is analyzed. The second, phenological phase in different years and zones is estimated based on greatest changes of slope method and EOF analysis method, and the result monitored by the two methods is compared, as a result, trend of growing season change from 1982 to 1999 in different latitude zones is better acquired. The third, phenological phase of vegetation in different spatial location from 1982 to 1999 is fitted based on curve. Then, spatial difference rules of growing season of every year and average of multi-year is discussed in article. In the end, lag correlation and linear regress are used to study relation between phenological phase of different types of vegetation, different latitude zones, different spatial places and climate changes.

利用阈值法和滑动平均法逐年估测了每种植被类型的生长季的开始、结束日期及长度；对18年中植被生长季的开始、结束时间和长度进行一次线性拟合，分析了植被生长季的开始、结束日期和长度的线性变化趋势；基于最大变化斜率法和EOF分析法估计了不同年份、不同区域内植被生长季的开始、结束时间及其长度，并对这两种方法的监测结果作了比较，从而得到了较好的不同纬度区域1982～1999年植被生长季的变化趋势；基于曲线拟合了1982～1999年的不同空间位置的植被物候期，然后讨论了每年和多年平均的植被生长季的空间分异规律；最后利用时滞相关分析和线性回归研究了不同类型植被的物候期与气候变化的相互关系，不同纬度带的植被物候期与气候变化的相互关系，植被物候期与气候变化空间相互关系。

Phenological data of 20 ligneous plants in Xi'an botanic garden from 1988 to 2002 was analyzed. The results showed that the spring phenological phenomena of all observed 20 ligneous plants had been earlier since 1988, while the autumn phenological phenomena of most observed 20 ligneous plants had been delayed. The response of the spring phenological phenomenon to the climate change was more obvious than that of autumn phenological phenomenon.

通过对1988-2002年西安市植物园20种木本植物物候资料的分析，结果表明：近十余年西安市植物园20种木本植物物候变化趋势明显表现为所有植物春季物候逐年提前、大多数植物秋季物候逐年推迟的趋势；春季物候对气候变化的响应程度显著大于秋季物候，大多植物生殖生长期的物候变化幅度大于营养生长期。

The results show that the phenological periods of ligneous plants occurred earlier with increasing temperature in spring; on the contrary, the ligneous plant phenological periods delayed with decreasing temperature.

结果表明：平均温度上升，木本植物春季物候期提前；平均温度下降，木本植物春季物候期推迟。

The results show that Phenological season in Minqin oasis can be divided into 4 major stages, and 12 sub-stages,winter long and autumn short, spring and summer mediacy in 4 major stages of spring, summer, autumn and winter,each season stage not only had obviously indicative Phenological phenomenaandtypical form combination of phenologicalphenomena, but also had unique seasonal aspects.

了解一个地区季节演变的特点和季节节奏变化的规律，对掌握一定地域内生物第一性生产力的高低和风景旅游资源的时序变化特点，合理组织和安排农、林、牧业生产活动，以及社会精神文化生活具有十分重要的意义。对季节的划分，目前比较流行的是以物候指标划分季节。

As to majority plants, the change extent of reproduction growing phenological changes was greater than that of nutrition growing phenological changes.

因此，春季物候和生殖生长期物候更加适宜作为气候变化的物候指标。

The effects of climate warming on plant phonological changes from 1983 to 2004 in Guangdong are studied by use of the plant phenological data and temperature data of 10 Agrometeorological stations in Guangdong of the same time. The models for relationship between phenological periods and temperature are constructed. The responses of the phenological period to climate change are analyzed.

根据广东省气象观测资料和10个农业气象观测站的物候观测资料，分析了1982～2004年温度变化对广东省木本植物物候变化的影响，并建立了物候期差异与温度之间的关系模式，分析了当前气候增暖背景下物候期对温度变化的响应关系。

Based on the plant phenological data of 26 stations from 1963 to 1996, observed by the phenological observation network of the Chinese Academy of Sciences, changes of plant phenological period and its response to climate change were studied. The models for relationship between phenological periods in every decade and geographical location were constructed.

根据中国科学院物候观测网络中 2 6个观测站点的物候资料，分析了近 40年我国木本植物物候变化及其对气候变化的响应关系，并建立了不同年代物候期与地理位置之间的关系模式，分析了当前气候增暖背景下物候期地理分布规律变化对气候变化的响应关系。
