Google Earth Engine在农业管理中的研究现状与展望

农业作为中国国民经济的战略性产业,在粮食生产和可持续发展目标方面起着举足轻重的作用。为了满足农业管理中大空间尺度、长时间序列遥感数据的存储、组织和处理,节省用户计算资源,提高农业生产管理专题的时效性和普适性,地理空间数据处理云平台备受关注。谷歌地球引擎（Google Earth Engine,GEE）作为一款集数据获取、数据运算、模型建立、精度验证以及可视化分析于一体的地理空间分析开源智能云平台,极大地扩展了农业领域研究的广度和深度,为精准农业领域的发展带来了新的机遇。本文从GEE平台、农业应用数据、作物种植支撑管理和农田管理工具等角度出发,分析了基于GEE平台的农业管理研究最新研究进展,以“平台-数据-农业管理-工具”为大框架,强调了多源协同的有效数据信息支撑农业监测管理决策的制定,高效易扩展的农田种植管理和作物生长监测工具可以辅助提高农业生产效率,农情数据信息和农业管理工具在全球背景下共同促进农业可持续发展。文章对GEE在农业应用数据支撑、农业监测管理和农田管理工具等方面的研究现状进行分析总结,突出了GEE云平台相比于传统的桌面端地理空间数据处理平台分别在数据、工具和应用3个方面给...

Traditional Ecological Knowledge and Community-based Natural Resource Management in Northeast India

Community-based natural resource management in northeast India has a long history. Indigenous knowledge and adaptation are the collective information, with improvement from generation to generation. The expectation is that under community control, local expertise on biodiversity will play a significant role in natural resource management through traditional practices. This paper discusses the characteristics and application of the traditional ecological knowledge of aboriginal peoples in northeast India and its role in natural resource management. Examples are provided in two different eco-cultural landscapes, i.e., Demazong (the Buddhist eco-cultural landscape in Sikkim Himalaya) and the Apatani eco-cultural landscape in Arunachal Pradesh, which illustrate the utility value of traditional ecological knowledge in sustainable natural resource management. Both eco-cultural landscapes are indeed very complex and highly evolved systems with high levels of economic and ecological efficiencies. The paper concludes that traditional ecological knowledge systems and institutions could serve as entry points into the sustainable utilization and management of natural resources. This could be achieved through the exploration of the cultural practices of the local people and integrating useful aspects into the modern natural resource management expertise. With rapidly depleting biodiversity in the developing tropic regions, there is a greater utilization today than ever before of the value of respecting the "Sacred" as a tool towards better conservation of natural resources.

Evaluation of nitrogen cycling associated with agricultural production and environmental load in a mountain region,in Hokkaido,Japan

This study examined the nitrogen cycling associated with agricultural production and environmental load in central Hokkaido. The nitrogen （N） budget analysis model offers a new set of tools for evaluating N cycling in agro-ecosystems. The cycling index （CI） is a useful tool for estimating optimal N flows in farmlands. The fertilization index （FI） is a useful indicator for characterizing the N flows related to farms. Using these parameters, we analyzed all farm systems to estimate the optimal N cycling for minimizing N pollution in groundwater and maximizing agricultural production in mountain regions of Japan. The results showed that the critical N application rate （chemical fertilizer ＋ manure） was 143.3 kg N ha^-1 y^-1. The critical inter-system input （chemical fertilizer N, imported food and feed N, and natural supplied N） was 169.2 kg N ha^-1y^-1.     

Geochronological review of Sambagawa metamorphic belt in Southwest Japan

Based on almost all available published age data, the protolith ages, peak metamorphic ages and cooling rate of the Sambagawa metamorphic belt have been discussed and the latest constraints on the ages of the Sambagawa metamorphism and subduction-related accretionary evolutions were summarized. Peak metamorphic conditions attained within the Kuma nappe complex at ca. 145-185 Ma, and uplift through ca. 500℃at ca. 150 Ma and 350-400癈 at ca. 110 -115 Ma. The protolith sediments of the Besshi nappe complex were accumulated and subsequently progressively subducted and suffered high P-T prograde metamorphism during the Kuma nappe complex uplifting. The Besshi nappe complex arrived maximum metamorphic conditions at ca. 110- 120 Ma and subsequently started rapid uplift with the cooling rate of ca. 14.2℃/Ma at ca. 75 -85 Ma, followed with the cooling rate of ca. 6.0-8.9℃/Ma. The Oboke nappe complex started subduction later than other tectonic units and arrived the peak metamorphic conditions at ca. 75 Ma, which followed by the uplift with a cooling rate of ca. 8℃/Ma.
