Perspective of Chinese GF-1 high-resolution satellite data in agricultural remote sensing monitoring

High-resolution satellite data have been playing an important role in agricultural remote sensing monitoring. However, the major data sources of high-resolution images are not owned by China. The cost of large scale use of high resolution imagery data becomes prohibitive. In pace of the launch of the Chinese ＂High Resolution Earth Observation Systems＂, China is able to receive superb high-resolution remotely sensed images （GF series） that equalizes or even surpasses foreign similar satellites in respect of spatial resolution, scanning width and revisit period. This paper provides a perspective of using high resolution remote sensing data from satellite GF-1 for agriculture monitoring. It also assesses the applicability of GF-1 data for agricultural monitoring, and identifies potential applications from regional to national scales. GF-1＇s high resolution （i.e., 2 m/8 m）, high revisit cycle （i.e., 4 days）, and its visible and near-infrared （VNIR） spectral bands enable a continuous, efficient and effective agricultural dynamics monitoring. Thus, it has gradually substituted the foreign data sources for mapping crop planting areas, monitoring crop growth, estimating crop yield, monitoring natural disasters, and supporting precision and facility agriculture in China agricultural remote sensing monitoring system （CHARMS）. However, it is still at the initial stage of GF-1 data application in agricultural remote sensing monitoring. Advanced algorithms for estimating agronomic parameters and soil quality with GF-1 data need to be further investigated, especially for improving the performance of remote sensing monitoring in the fragmented landscapes. In addition, the thematic product series in terms of land cover, crop allocation, crop growth and production are required to be developed in association with other data sources at multiple spatial scales. Despite the advantages, the issues such as low spectrum resolution and image distortion associated with high spatial resolution and wide swath width, might pose challenges for GF-1 data applications and need to be addressed in future agricultural monitoring.

[Objective] The aim was to study the influence of abnormal climate in Fushun City in 2010 and its influences on agriculture.[Method] In response to the abnormal climate in Fushun in 2010,the atmosphere circulation characteristics of abnormal climate and their influences on each aspect of agriculture were expounded.[Result] The abnormal weather in Fushun City in 2010 was as follows:extreme low temperature in spring,much precipitation,more precipitation in each month,less sunshine hours,abnormally less precipitation in July and August,having five times of heavy rain.The main atmosphere circulation features were extreme strong of vortex in March and frequent cold air activity;strong high pressure ridge in Mountain Ural in Middle April,west and strong east Asian Trough and strong front in middle and north part of Asia;middle and high latitude in Asia in May was wide trough region.The subtropical high ridge of the north front was more north than that in other common years and the position of west ridge was more conductive to the transportation of water vapor and formation of rain;because of extreme strong vortex in July and August,subtropical high was conductive to the cold air in the north moving south and the transportation of south water vapor.The extreme climate brought adverse influences on each aspect of agriculture and resulted into large economic losses.[Conclusion] The study provided references for the improvement of abnormal climate forecast and disaster prevention capacity.

The Theoretical Connotation and Systematic Essence of Core Competence of Agricultural High-tech Enterprises

Six representative interpretations about the core competence of the corporate proposed by the researchers both at home and abroad from different perspectives are introduced,which includes "Resource theory","Capacity theory","Integration theory of assets and mechanism","Theory of consumer surplus","Theory of institutions and systems" and "Theory of innovation". It is pointed out that although these interpretations play an active role in enriching the theory of core competence,it still faces the problems to further deepen these interpretations:the first problem is how to give a precise definition;the second is about its extension;the third is on the logical and practical relationship between the production mechanism and its sustainable competitive advantages;the fourth is the problems in the production process and the corresponding management. Both the systematic essence and features of core competence are introduced:the first is the system self-organization process produced within the corporate;the second is the interaction between corporate system and environment;it needs a growing and evolution process. This paper briefly describes the essence of core competence of agricultural high-tech corporate,introduces its five features including systematicness,integration,non-imitation,ductility and non-equilibrium,and finally explains its component parts,mainly including corporate culture system,technological innovation system,human resource system,management capability system,corporate production and marketing system,financial capability system and adaptability system.

农地流转提升了农业绿色全要素生产率吗?

在2006-2021年中国30个省份的面板数据基础上,本文通过SBM-GML超效率模型测算中国各省份农业绿色全要素生产率。采用双向固定效应模型和工具变量模型等方法,实证分析农地流转和农业绿色TFP之间的内在联系,并分析其影响路径机制。研究发现,中国农业绿色全要素生产率能够持续增长的主要原因在于技术进步。而农地流转能够推动农业绿色全要素生产率增长则是得益于技术效率改进。从异质性分析来看,农地流转对农业绿色全要素生产率增长的促进作用最显著的是东部地区和非粮食主产区,但在西部地区却正好相反。因此,中国应当加快推进农地流转工作进展,促进农业生产和经营管理模式变革,加快研发、推广和应用农业绿色生产技术,构建区域协作互助机制促进地区交流,进而促进农业绿色全要素生产率的提高。

山地生态农业高质量发展面临的困境与出路——以加榜梯田考察为例

发展在本质上是资源盘活及资源价值的变现,而资源盘活是发展的问题起点。拥有丰富资源却缺失让资源价值得以变现的产业植入,必然导致资源闲置或资源低效益利用。从江加榜梯田的个案表明,山地生态农业目前还存在产业单一、技术含量低、生产劳作条件差、劳动力大规模转移致使劳力不足以及农产品价格低,市场空间窄小等不利因素。面临这样的发展困境,只有对山地生态农业产业链进行升级打造,实现农文旅融合发展,才能发挥以梯田为代表的山地生态资源优势,进而为山地生态农业高质量发展找到可行的路径依托。
