利用遥感技术获取植被覆盖度与气候因子关系，可为改善研究区域生态环境提供

利用遥感技术获取植被覆盖度与气候因子关系，可为改善研究区域生态环境提供参考。本研究基于西昌市2014年Landsat8影像4个季度数据，获取地面植被覆盖度，结合同时期的气象资料，从空间上分析西昌市植被覆盖度对气候因子的响应，结果显示西昌市植被覆盖度整体较可观，低覆盖率植被在第一季度到第三季度明显减少，高覆盖率植被在第二季度到第四季度整体增加；植被覆盖指数变化和降水、气温呈正相关，其中与降水量相关系数达到0.5200以上，呈显著或极显著正相关，与气温仅在第三季度呈显著正相关。说明影响西昌地区的植被生长气候因子主要是降水，其次是气温。

Relationship between vegetation cover and climate factors in remote sensing technology and can provide references to improve ecological environment in the study area. This research based on Xichang city 2014 Landsat8 image 4 a quarter data, gets ground vegetation cover degrees, combined with period of meteorological information, from space Shang analysis Xichang city vegetation cover degrees on climate factor of response, results displayed Xichang city vegetation cover degrees overall more considerable, low coverage vegetation in first quarter to third quarter obviously reduced, high coverage vegetation in second quarter to IV quarter overall increased; vegetation cover index changes and precipitation, and temperatures is are related, Correlation between precipitation over 0.5200, was a significant or very significant positive correlation was positively correlated with temperatures only in the third quarter. Instructions affecting vegetation growth and climate factors in Xichang area mainly precipitation, followed by temperature.

Using remote sensing technology to obtain the relationship between vegetation coverage and climate factors can provide reference for improving the ecological environment in the study area. The Xichang City in 2014 landsat8 images of of four quarter data based on, gain ground vegetation coverage, node contract period of meteorological data, from the space analysis of Xichang City, vegetation cover degree of response to climatic factors. Results show that Xichang City, vegetation cover degree is considerable, low vegetation coverage in first quarter to the third quarter decreased significantly, the high vegetation coverage to the fourth quarter of the overall increase in the second quarter; vegetation index change and the precipitation and temperature was positively related, the precipitation correlation coefficient reached more than 5200, were significantly or extremely significantly positive correlation, and temperature only in the third quarter was significantly and positively correlated. It shows that the vegetation growth climate factors in Xichang area are mainly precipitation, followed by temperature.
