文摘The cognition and attitudes of resources environment affect environmental behavior of behavior subject,the changes of attitude and behavior become one of the key factors of influencing harmonious and healthy development of ecological environment. With PRA survey method for obtaining questionnaire data and based on behavior geography and social psychology theory,farming-pastoral,dry grassland,desert grassland, typical project village alpine grassland of returning fazing land to grasslands as an example,with main body cognitive perspective of the aid of resources,the article analyzed space dissimilation of stakeholders environmental cognitive and behavior preference response in the area of returning grazing land to grasslands from ecological environment from policy environment,ecological environment and family economic environment aspects. The results showed that： stakeholders judgment of Grassland degradation in different ecological function area had obvious regularity,the cognitive proportion of Grassland degradation gradually increase from farming-pastora to alpine savanes. The satisfaction from returning grazing land to grasslands showed a changing tendency of reversed U. stakeholders had more strongly negative cognition in the area of dry steppe and desertsteppe. From farming-pastoral to alpine savanes,the economic environment tend to worse situation. Negative environmental behaviors tend to increase,Positive behavior on the contrary.
文摘利用2000—2016年的MODIS数据,对呼伦贝尔生态功能区环境质量变化时空格局进行分析。结果表明,研究区光合有效辐射(FPAR)、叶面积指数(LAI)在过去17年间整体较稳定,FPAR均值在0.7 W/m 2附近波动,LAI均值在2.8附近波动。总初级生产力(GPP)、净光合速率(PsnNet)整体上呈现缓慢增加的趋势,最大值均出现在2014年,分别为0.044、0.035 kg C/m 2;最小值均出现在2003年,分别为0.028、0.021 kg C/m 2。空间格局上,FPAR、LAI、GPP和PsnNet的指标值呈自西向东逐渐增加的趋势。该研究为呼伦贝尔生态功能区草地退化遥感监测提供技术方法。
