浅析国有土地收购价格内涵界定

一、国有土地收购价格内涵及定位 土地收购价格内涵从本质上来说是国家和土地使用者利用各自权利参与社会剩余价值分配的结果,它所内含的价值量只是土地实际价值的一部分。由于土地收购性质定位不同,收购价格确定的方法、依据以及价格内涵也将不同,所以土地收购价格的内涵界定需在明确土地收购性质的前提下进行。     

Temporal variability of temperature-nitrate relationship in a coastal region

The inverse relationship between nitrate and temperature （N-T relationship） has been used to estimate new production from remotely sensed sea surface temperature at the regional or global scale of oceans. This study aimed to develop a time-series model of the N-T relationship from automated, continuous hourly observations over two years on the coast of Halifax, Canada. The model demonstrated time-series variability of the N-T relationship at a coastal station on the Nova Scotia Shelf, with adjusted R2=0.999 4 and RMSE=0.025 7. The maximum residual value was 0.077. The annual temperature variations described a sine curve, and daily, weekly, and monthly variations fluctuated within the normal ranges, controlled by the local climate. The annual variation of nitrate concentration formed nearly a sine curve. Heavy or long- lasting rainfall increased nitrate concentration by 4 to 30-fold in 24 h, and then the increased nitrogen was quickly depleted by phytoplankton growth in 10 to 48 h. In general, biological activity was a key factor in causing nitrate concentration change, dependent mainly on seawater temperature. The power function of the N-T relationship observed in our study area could be used to quickly estimate sea surface nitrate concentration, in combination with temperature data obtained by remote sensing.

基于文化资本的地名档案信息资本化途径探析

一、资本、文化资本与资本化概念及相关论述 按照马克思主义政治经济学的观点,资本是一种可以带来剩余价值的价值,它在资本主义生产关系中是一个特定的政治经济范畴,泛指一切投入再生产过程的有形资本、无形资本、金融资本和人力资本。资本的主要特征是一种运动。也就是通过资本运营,
