In this paper,a methodology for Leaf Area Index(LAI) estimating was proposed by assimilating remote sensed data into crop model based on temporal and spatial knowledge.Firstly,sensitive parameters of
选择古尔班通古特沙漠南缘典型丘间低地荒漠草地,采用完全随机区组设计,通过设置8个肥料添加处理(CK、N、P、K、NP、NK、PK、NPK),研究了荒漠草地植物多样性对不同肥料添加处理的响应,得出以下结论:(1)研究区植被丰富度指数在P、NP、PK肥添加的作用下显著增加,而其余处理对其影响不显著,NK处理使研究区植被丰富度指数下降;多度指数在不同肥料添加下表现出与丰富度指数相同的特征;(2)不同施肥
Phosphorus fractions and adsorption-release characteristics of sediments in the Zhujiang(Pearl) River estuary wetland were investigated.Results showed that the total phosphorus(TP) content in surface

Land use/cover change is an important parameter in the climate and ecological simulations. Although they had been widely used in the community,SAGE dataset and HYDE dataset,the two representative glob
It is believed that the global CO2emissions have to begin dropping in the near future to limit the temperature increase within 2 degrees by 2100. So it is of great concern to environmentalists and nat
Understanding the driving forces and mechanism of land use change is a key issue in land change science,and has received much attention over the past 30 years. While many driving forces have been iden
