摘　　要：为了测量1.8%阿维菌素2000~3000倍液农药对商丘森林公园虫害抑制效果。利用森林公园内植物在近红外波段具有高反射特性及在红色可见光范围内具有低反应特性,采用归一化植被指数初步完成植物所在区域提取步骤,通过蓝噪声理论中遥感植被图像纹理测量方法确定其是否属于森林区域;并以此聚类中心作为遥感图像最优纹理特征完成对此区域内病虫害扩散趋势图像的分析。实验证明,运用该方法能有效分析1.8%阿维菌素2000~3000倍液农药使用环境下,商丘森林公园中病虫害扩散趋势。In order to measure1.8%abamectin2000~3000times liquid of pesticide inhibition effect to shangqiu forest park of insects.Using forest park plant in near infrared wave band with high reflection characteristic and in the red visible light range with low response characteristics,using the normalized difference vegetation index completed preliminary plant area extraction steps,through the blue noise theory of vegetation remote sensing image texture measurement method to determine whether it belongs to the ginkgo tree area;Ginkgo tree by Gabor transform of plant image in all directions in the area ofdiscrete image pixels to obtain sorting coefficient of amplitude,according to the clone algorithm selection,clone and mutation way so as to obtain the optimal clustering center,plant diseases and insect pests image and the optimal clustering center as a remote sensing image texture feature complete plant diseases and insect pests spread trend analysis of the image to this area.Experiments show that using this method can effectively analyze1.8%abamectin2000~3000times liquid of pesticide use environment,trend of shangqiu diffusion plant diseases and insect pests in forest park.
