Land-Use Classification via Transfer Learning with a Deep Convolutional Neural Network

Land cover classification provides efficient and accurate information regarding human land-use, which is crucial for monitoring urban development patterns, management of water and other natural resources, and land-use planning and regulation. However, land-use classification requires highly trained, complex learning algorithms for accurate classification. Current machine learning techniques already exist to provide accurate image recognition. This research paper develops an image-based land-use classifier using transfer learning with a pre-trained ResNet-18 convolutional neural network. Variations of the resulting approach were compared to show a direct relationship between training dataset size and epoch length to accuracy. Experiment results show that transfer learning is an effective way to create models to classify satellite images of land-use with a predictive performance. This approach would be beneficial to the monitoring and predicting of urban development patterns, management of water and other natural resources, and land-use planning.

Survey on the Peasants' Will of Forest Land Transfer in the Reform of Collective Forest Right System——On the Case of 180 Peasant Households in Lishui City of Zhejiang Province

Taking sample survey in the eighteen villages of Yunhe, Longquan and Qingyuan County of Lishui City of Zhejiang Province, the results show that the forest land transfer of sample peasants is mainly transfer-out, the private treaty of forest land transfer is the main pattern of most peasant households, forest right trading market hasn't got wide approval in peasants, peasants' dependence on land is reducing, and so on. Through analysis, the reasons of influent transfer of forest land include peasant's subjective will, less type of transfer objects, dull information communication, big difference of expected price and imperfect development of intermediary organization.

Empirical Analysis on Transfer and Limitation of Land Contractual Management Right

Existing laws have three limitations on transfer of land contractual management right. The survey of 506 farmer households in Zhejiang,Jiangxi and Guangxi provinces indicates that most farmers have the consistent knowledge of limitation on " transfer being approved by the party giving out the contract in advance" with legislative requirements,but it is not effectively implemented in actual operation. As to limitation on transferee,no matter in cognition of farmers,or in real transfer process,the transferee is not totally limited to farmers engaged in agricultural production and management. For the constraint that the transferor should have stable non-agricultural occupation or stable income source, most farmers agree,but more than half of the farmers have not confirmed the transfer action in practice.

Optioning Water Rights:A Potential Alternative to the Hanjiang-Weihe River Water Transfer Project,China

China has started shifting from relying on supply management to demand management strategy in addressing its water shortage problems.Water option,a financial derivative for water commodity,has been utilized to manage water demands in the United States and Europe since the 1990 s but is still novel to China.In this study we analyzed the pros and cons of China’s existing system for water rights transfers and proposed an alternative,flexible trading instrument-water options for China.Incorporating the uncertainty to water option pricing,this study first conducted an empirical analysis of the water option in the water-receiving area of the Hanjiang-Weihe River Transfer Project of China,and then evaluated the benefits of the water option applications.Results show that water option trading can bring water cost saving and increase the potential industrially added value for industrial enterprises in the receiving area,and trading of short-and-medium term water options is more favorable than the long-term water options trading.The novel water option trading proposed in this study,once verified through pilot studies,will be helpful in addressing water shortage problems in China.

The Way to Optimize the Right to Personal Data Portability in Chinese Practice——Based on Empirical Analysis of the Privacy Policies of 66 Mobile Apps

Although the existing legal norms and judicial practic-es can provide basic guidance for the right to personal data portabili-ty, it can be concluded that there are obstacles to the realization of this right through empirical research of the privacy policies of 66 mobile apps, such as whether they have stipulations on the right to personal data portability, whether they are able to derive copies of personal in-formation automatically, whether there are textual examples, whether ID verification is required, whether the copied documents are encrypt-ed, and whether the scope of personal information involved is consis-tent. This gap in practice, on the one hand, reflects the misunderstand-ing of the right to personal data portability, and on the other hand, is a result of the negative externalities, practical costs and technical lim-itations of the right to personal data portability. Based on rethinking the right to data portability, we can somehow solve practical problems concerning the right to personal data portability through multiple measures such as promoting the fulfillment of this right by legislation, optimizing technology-oriented operations, refining response process mechanisms, and enhancing system interoperability.

The Plights and Solutions of the Farmers' Land Rights Protection

Issues concerning Farmland Transfer in the Development of China's Agricultural Modernization——Based on the Survey of Farmers in 21 Townships of Sichuan Province

Based on the actual survey of 724 rural households in 21 townships of Sichuan Province,this article analyzes the basic information,basic characteristics and problems in current China's farmland transfer.The results show that the rural land contractual management right is relatively stable;in farmland transfer market,the degree of development of farmland transfer-out market is higher than that of farmland transfer-in market;at the same time,there are many problems,such as fragmentation of rural land resources allocation,incomplete land property rights system,too powerful land security function,single land transfer pattern and unsound transfer system.Corresponding countermeasures are put forward as follows:unifying urban and rural planning,and adjusting distribution pattern of rural land in concert with the course of urbanization;improving land property rights system,so that the farmers have the land contractual management right with real right tendency;strengthening the legal construction of land transfer,regulating the land transfer process,and guiding regularized and legalized development of land transfer;promoting farmers' cognitive level,and establishing the intermediary platform to provide land transfer information,ensuring information symmetry between both sides of transfer;providing more non-agricultural jobs,establishing and improving social security system for farmers,and diluting the social security function of land.

A Summary of Research on the Realization Process of "Separation of Three Rights" of Rural Land

In order to comply with the needs of rural social and economic development,promote new industrialization,informatization,urbanization and agricultural modernization,and realize industrial transformation,the central government clearly puts forward that the traditional ' separation of two rights' mode of rural land( collectives have ownership and farmers have contracting management right) should be transformed into the ' separation of three rights' mode( collectives have ownership,farmers have contracting right,and operators have management right) to solve the problems of farmers’ financing difficulties and agricultural land abandonment,promote the moderate scale operation of agriculture,and improve land use efficiency. It is found that the following points should be noted in the later stage of realizing the ' separation of three rights' of rural land. Firstly,the transfer of farmland management right in the process of realizing the ' separation of three rights' faces market risk,system design flaws,policy coordination failures and other problems. Secondly,the impact of implementation of ' separation of three rights' on rural and social development should also be noted.

Reform of Agricultural Land Transfer of Different Types of Farmers' Willingness

Since forty years of reform and opening up,China's rural landscape has undergone tremendous changes,and agricultural production manner is obviously improved,while farmers' living level is rose significantly.Rural land contracting and management right system plays a vital role in promoting rural economic and social development in China.In this paper,farmers under the background of the transfer of rural land contracting and management right are taken as research objects,and the difference of different types of farmers under the willingness of land transfer is analyzed.Finally,corresponding reform assumptions are proposed for transfer willingness of different types of farmers.

Defect and Innovation of Water Rights System

The rare deposition of water resources conflicts with its limitless demand. This determined the existence of the water rights transaction system. The implementation of the water rights transaction system requires clarifying the definition of water resource right above all distinctly. At present, it is a kind of common right system arrangement which needs the Chinese government to dispose of water resources. Though a series of management systems guaranteed the government＇s supply of water resource, it hindered the development of the water market seriously and caused the utilization of water resources to stay in the inefficient or low efficient state for a long time. Thus, we should change the government＇s leading role in the resource distribution and really rely on the market to carry on the water rights trade and transaction. In this way, the water rights could become a kind of private property right relatively, and circulate freely in the market. As a result of this, we should overcome the defects of common right, make its external performance internalized maximally and achieve the optimized water resource disposition and use it more effectively.

Path Choice of Rural Land Transfer in China

Establishing rural land collective property right system with clear ownership,complete powers and functions,smooth transfer,and strict protection is the basic guarantee to the equal exchange of land elements. In this study,the reform of relevant legal systems to China's rural land transfer was introduced firstly,and then the guiding ideology of China's rural land transfer was proposed. Finally,the ways of practicing rural land transfer in China were discussed. Based on the premise of insisting on and improving the strictest land preservation system,farmers should have the right to occupy,use,and transfer their contracted land,and they can transfer their land contracting and management right in ways of exchange,subcontracting,renting,stock cooperation,and trust. Exploring the ways of equal exchange of land elements according to local conditions is an important political and economic issue concerning the livelihood and development of farmers in China,so it should be conducted under the guidance of the correct ideas to integrate scattered land in China's rural areas,develop moderate-scale management,shorten the income gap between urban and rural areas,and realize balancing development of urban and rural areas in China.

What defines non-outstanding shares transfer premium in China？

We study the sample of 311 non-outstanding shares transfers from 2003 to 2004. The object of this study is to determine the extent to which premium can be explained by financial factors of firms. The intrinsic value of transferred shares with control right is different from the others. We find that the larger percent of share transferred, the higher premium will be paid. Current liability ratio interpreting the premium of non-outstanding shares transfers is negative related to short term debt. Price ratio can determine the premium level when the ratio of transfer share under 30 percent

论居住权处分权能的适用价值与立法探析

我国《民法典》对于居住权的处分权能采取绝对禁止适用原则。承袭于罗马法的我国居住权制度以人役性的社会保障为其制度功能起点,旨在完善我国的住房保障体系、实现“住有所居”的政策目标。通过分析司法实践中居住权出现的新模式以及域外典型国家居住权制度的发展演进过程,可以发现居住权处分权能在我国有着破除限制条件的现实价值。应在居住权类型化的基础之上,从居住权的多重制度功能角度出发,采取“三编协同”——即物权编、婚姻家庭编和继承编衔接之立法体例,对居住权处分权能的扩张进行针对性规范。在保证原有立法目的得以实现的前提下发挥居住权制度经济效益,为投资性居住权的发展提供法律支撑,凸显居住权用益物权之本质。

主体资质欠缺之采矿权转让合同效力的裁判路径与规则重塑

主体资质欠缺之采矿权转让合同效力裁判路径的多样性与理论证成的多元性构成了司法实务的难点。主体资质欠缺之采矿权转让合同效力的判断与未经审批之采矿权转让合同效力的判断具有牵连性,但又呈现出独立的规则特征,其裁判路径的多元性以及理论阐释的多样性,决定了研究价值的继续存在。裁判规则的统一、诚信守约人的保护以及采矿权高效流转等价值目标对裁判规则的重塑提出制度供给的需求。《矿产资源法》修订应注意区分采矿权资质对采矿权持有与行使的不同关系,完成主体资质与合同效力的松绑,实现采矿权转让主体资质与采矿权转让合同效力的彻底剥离,同时应明确规定采矿权转让合同原则上自成立之日起生效,避免解释论层面的不必要纷争。此外,《矿产资源法》修订需严格绑定主体资质与采矿权行使的关系,将国家对矿业秩序的要求植入采矿权的具体行权过程。司法实践可考虑适用《民法典》第215条确立的区分原则,采合同有效说作为修法尚未完成的过渡方案。

Agricultural Land Contract and Management Rights:Transferring Price and Countermeasures in Typical Agricultural Areas of China

Henan is a large agricultural province and one of China’s major grain-producing areas. Agricultural land transfer and large-scale operations will have a profound impact on regional economic development and food security. This is a case study taken in Xiwan village in Qinyang city, Henan. This paper builds a transferring pricing model using land use rights assessment and characteristic correction of land contract and management rights. Results show that the transferring price of land contract and management rights should include the economic price, social price and corrected price. The use of a price model should focus on the distinction of theory and practical application. If there is no change in agricultural project,the actual transferring price should be the sum of the economic price and social security price. If there is a change in agricultural projects,such as cropland into cash crops,the actual transferring price should be the sum of the economic price, social price and corrected price. Because of the complexity of income distribution following the transfer, transferring gains should follow a rational distribution in the outflow side, inflow side, managers and land owner. The government should establish reasonable and orderly contracted management of land circulation transferring and use this to build a land transferring price system.
