| 1 | Optimization of Land Use Structure Based on Ecological GREEN Equivalent显示文摘Optimization of land use structure consists of economic and social and ecological optimization.Applying the minds of system engineering and principles of ecology,this paper presents such thoughts:the optimal forest_coverage rate calculated according to the reality of a district is set as main standard of ecological rationality in the district;through considering the value of ecosystem services of the land with GREEN equivalent (mainly cultivated land and grassland)and based on the rule,GREEN equivalent,this paper introduces the area conversion between woodland and cultivated land,also between woodland and grassland;this paper establishes a multi_dimension controlling model of optimization of land use structure.In addition,a multi_objective linear programming model for optimization of land use structure is designed.In the end,this paper tests and verifies this theory of ecological optimization,taking Qionghai city in Hainan Province as an example. | LIU Yanfang MING Dongping YANG Jianyu | 2002 | Geo-Spatial Information Science2002,5,4: | 7 |
| 2 | Using irrigation intervals to optimize water-use efficiency and maize yield in Xinjiang,northwest China显示文摘Worldwide, scarce water resources and substantial food demands require efficient water use and high yield.This study investigated whether irrigation frequency can be used to adjust soil moisture to increase grain yield and water use efficiency(WUE) of high-yield maize under conditions of mulching and drip irrigation.A field experiment was conducted using three irrigation intervals in 2016: 6, 9, and 12 days(labeled D6, D9, and D12) and five irrigation intervals in 2017: 3, 6, 9, 12, and 15 days(D3, D6, D9, D12, and D15).In Xinjiang, an optimal irrigation quota is 540 mm for high-yield maize.The D3, D6, D9, D12, and D15 irrigation intervals gave grain yields of 19.7, 19.1–21.0, 18.8–20.0, 18.2–19.2, and 17.2 Mg ha^-1 and a WUE of 2.48, 2.53–2.80, 2.47–2.63, 2.34–2.45, and 2.08 kg m-3, respectively.Treatment D6 led to the highest soil water storage, but evapotranspiration and soil-water evaporation were lower than other treatments.These results show that irrigation interval D6 can help maintain a favorable soil-moisture environment in the upper-60-cm soil layer, reduce soilwater evaporation and evapotranspiration, and produce the highest yield and WUE.In this arid region and in other regions with similar soil and climate conditions, a similar irrigation interval would thus be beneficial for adjusting soil moisture to increase maize yield and WUE under conditions of mulching and drip irrigation. | Guoqiang Zhang Dongping Shen Bo Ming Ruizhi Xie Xiuliang Jin Chaowei Liu Peng Hou Jun Xue Jianglu Chen Wanxu Zhang Wanmao Liu Keru Wang Shaokun Li | 2019 | The Crop Journal2019,7,3: | 4 |
| 3 | Single‑Atom Cobalt‑Based Electrochemical Biomimetic Uric Acid Sensor with Wide Linear Range and Ultralow Detection Limit显示文摘Uric acid(UA)detection is essential in diagnosis of arthritis,preeclampsia,renal disorder,and cardiovascular diseases,but it is very challenging to realize the required wide detection range and low detection limit.We present here a single-atom catalyst consisting of Co(Ⅱ)atoms coordinated by an average of 3.4 N atoms on an N-doped graphene matrix(A-Co-NG)to build an electrochemical biomimetic sensor for UA detection.The A-Co-NG sensor achieves a wide detection range over 0.4-41,950μM and an extremely low detection limit of 33.3±0.024 nM,which are much better than previously reported sensors based on various nanostructured materials.Besides,the A-Co-NG sensor also demonstrates its accurate serum diagnosis for UA for its practical application.Combination of experimental and theoretical calculation discovers that the catalytic process of the A-Co-NG toward UA starts from the oxidation of Co species to form a Co^3+-OH-UA*,followed by the generation of Co^3+-OH+^*UA_H,eventually leading to N-H bond dissociation for the formation of oxidized UA molecule and reduction of oxidized Co^3+to Co^2+for the regenerated A-Co-NG.This work provides a promising material to realize UA detection with wide detection range and low detection limit to meet the practical diagnosis requirements,and the proposed sensing mechanism sheds light on fundamental insights for guiding exploration of other biosensing processes. | Fang Xin Hu Tao Hu Shihong Chen Dongping Wang Qianghai Rao Yuhang Liu Fangyin Dai Chunxian Guo Hong Bin Yang Chang Ming Li | 2021 | Nano-Micro Letters2021,13,1: | 2 |
