Precision seeding technology is one of the important technologies to realize cost saving and efficiency increasing in large-scale production. Precision direct seeding of rice has gradually become the main research direction of rice light and simplified planting. The real-time sowing monitoring system has an important contribution to improve the sowing quality of direct seeding machine, and can provide important support for the research and development of sowing rate real-time adjustment, real-time reseeding and the seeding evaluation quality system of rice precision direct seeding machine. At present, the methods of seeding monitoring are photoelectric-based, image-based and capacitance-based. However, image processing technology requires special equipment with high cost, and cameras are easy to be interfered by external light. For the capacitance-based method, when multiple small seeds fall simultaneously, the monitoring performance is not accurate enough. In order to monitor the sowing rate of precision rice hill-drop drilling machine in real time, in this paper, the surface-type photoelectric sensor installed in the seeding tube is used as the main monitoring element to design the monitoring system of precision rice hill-drop drilling machine. According to the structure and working principle of seed metering device, the installation modes of photoelectric sensor and rotary encoder are determined. In this system, the seeds flow in the seeding tube is taken as the research object. When the rice seeds pass through the photoelectric sensor monitoring area, it will cause the change of infrared beam intensity, which will lead to the change of photoresist voltage. The pulse signal from the photoelectric sensor is used as the time sequence to capture the interruption source, and then the monitored time sequence of rice seeds flow is obtained. The time division node is obtained by the synchronous monitoring of the seed metering time series and the rotation speed of the seed metering device. Based on the two adjacent time dividing nodes, the detecting time window of the seeds number per hill is obtained, each time window corresponds to one hill. The pulse width time of the rice seeds output in the monitoring time window is analyzed to get the seeds number per hill. Compared and analyzed the manual statistical data with the monitoring system statistical data, the test results show that the rotation speed of the seed metering device has a great influence on the monitoring accuracy of the average seeds number per hill, the variation coefficient of the monitored value of the average seeds number per hill grows up with the increase of the rotation speed of the seed metering device. When the rotation speed of seed metering device is 25-65 r/min, the relative error of seeds number per hill is less than 7.99% for Nanjing 46 (short grain variety), the monitoring errors of the number of hills is less than 6.07%; the relative errors of seeds number per hill is less than 24.07% for Xiangyaxiangzhan (long grain variety), the monitoring errors of the number of hills is less than 5.66%. The test results show that sowing rate monitoring system is applicable to different varieties of seed and has good detection accuracy, which can provide reference for improving the operation quality of precision rice direct seeder.

Ecological conservation redline (eco-redline), the region with special and important ecological functions in the ecological space, must be strictly protected. According to the theory of ecology, only in a well- structured and healthy ecosystem, can the ecological function be brought into full play and the ecological security be guaranteed. Therefore, the ecosystem health of eco-redline is the basis of maintaining regional ecological security. Based on the data of land use/cover and remote sensing images in years of 2000, 2005, 2010 and 2015, this paper evaluated the ecosystem health of the eco- redline in Nanjing from five aspects: vigor, organization, resilience, ecosystem service function and anthropogenic stress. The results show that: (1) The areas of forest land, farmland, water bodies, construction land, wetland and grassland in eco-redline in the study area were 511.74 km2, 456.96 km2, 432.58 km2, 118.0 km2, 32.79 km2 and 1.56 km2, respectively. The area of forest land continued to increase, while that of farmland decreased gradually. (2) From 2000 to 2015, the average ecosystem health index of eco-redline in Nanjing was 53.83, above the sub-health level, and showing a slow growth trend. (3) The ecosystem health index of terrestrial ecosystem was higher, especially in the areas with large forest vegetation coverage, compared with aquatic ecosystem. [ABSTRACT FROM AUTHOR]

Rural areas play an important hinterland role in social development, and the evolution of rural spatial structure has an important impact on the function of rural ecological services. Taking Nanjing as an example, this paper conducts the research on the evolution of rural regional ecological service functions based on the scope of physical rural areas. The remote sensing quantitative measurement and CASA model are used to calculate and analyze the evolution of rural regional ecological service functions in Nanjing from 1985 to 2016. The results show that: (1) From 1985 to 2000, the value of various functions of rural ecosystem services declined in varying degrees; from 2000 to 2016, the values of all kinds of functions, except that of water conservation function, still showed a downward trend. (2) In the first stage, the decline of rural ecological service function was mainly found in the south, west to south and east to south. In the second stage, except for the increase of ecosystem services in the north and northwest directions, the decline of ecosystem services in all directions decreased in varying degrees. (3) In the stage of industrialization of villages and towns, the change of land use structure within villages had a major impact on the ecological service function. In the stage of urbanization, the impact of urban expansion on rural ecological service function was the main aspect. [ABSTRACT FROM AUTHOR]

In the urbanization of China, construction land is generally distributed as a continuous area, and its change shows distinct spatial aggregation leading to the strong spatial autocorrelation, which is more obvious in remote sensing imagery with a fine spatial resolution. Based on the TripleSat-2 multi-spectral remote sensing images covering Nanjing city in 2016 and 2017, the paper compares and analyzes the performance of remote sensing change detection of construction land after we introduced the spatial autocorrelation index of the change vector as the image feature. Firstly, the three typical spatial autocorrelation indices of local G, Moran's I and Geary's C are extracted, and then the optimal spatial range of Lag and the optimal autocorrelation index suitable for the change detection are determined. The results showed that: (1) The spectral change vector had significant positive correlation. (2) The optimal range of Lag can be determined by global Moran's I and semi-variance. (3) We used the local G and local Moran's I with the spectral change vectors to increase the F1 score of the change detection, and the local G showed the better performance. (4) Using the local G with the optimal range of Lag as additional image features, the F1 scores were 20% higher than that using only the spectral change vectors. Fusing local spatial autocorrelation information especially of the multi- scale local G as the additional image features can effectively improve the change detection accuracy of construction land in remfote sensing imagery.
