中文摘要:利用2000—2012年气温、降水量、归一化植被指数(NDVI)数据,对科尔沁沙地气候与植被变化特征及其定性与定量响应关系进行了分析。结果表明,研究区植被长势自东向西逐渐变差有28.56%的面积呈变差趋势,其余呈变好趋势;多年植被长势呈变好趋势,降水呈微弱增加趋势,气温变化趋势不明显。累积2~3个月降水量、当月及平均2~3个月气温对植被影响较大;降水量增多、年内4—11月份气温升高、4—8月份单月年际变化中4月最低气温升高和6—8月份平均、最高气温降低,均促进植被生长;水热同期比单独因子变化对植被影响更大。NDVI在0.03~0.33时受气温影响显著;在0.33~0.43时受降水量影响显著;在0.43~0.62时受水热共同影响显著;在0.53~0.62时气温升高会抑制生长。当降水、气温分别在一定范围内变化,或在一定范围内变化时的水热共同作用下,NDVI响应于一定范围,且部分响应范围间有共同的重叠响应区域。

Abstract:Making full use of the air temperature, precipitation, normalized difference vegetation index (NDVI) data during 2000 to 2012, the variation of climate and vegetation in Horqin sandy land, as well as the response relationship between vegetation and climate factors were analyzed by qualitative and quantitative methods. The results showed that the vegetation in the region deteriorated gradually from east to west, the area of vegetation growth deteriorated accounted for 28.56% of the research area, and the vegetation growth of the remained area showed ameliorated trend. Perennial vegetation grew well with NDVI, while the precipitation increased faintly and the temperature variation trend was not obvious. The vegetation growth was influenced greatly by 2~3 months accumulated precipitation, the temperature of the month and average temperature of 2~3 months. The vegetation growth was promoted by the following factors, including precipitation increment, temperature rising during April to November, the lowest temperature increment in April compared with inter-annual variation of April to August, as well as the highest or the average temperature decrease from June to August. When NDVI was 0.03~0.33, the vegetation growth was influenced obviously by temperature, when NDVI was 0.33~0.43, it was influenced obviously by precipitation, when NDVI was 0.43~0.62, it was influenced by both temperature and precipitation, however, when NDVI was 0.53~0.62, it was inhibited by the rising temperature. NDVI responded to the changes of precipitation or temperature or combined action of precipitation and temperature in different response ranges, which might overlap.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
