East gate, three qing 5 mu two fen five li6 hao3 si4 silt higher can not get, changed to dry field, per mu rent 3 qian)5 [22] is usually a text sample. Soon after productive info screening, text samples of 147 effective plots have been ultimately obtained. Then, the word segmentation in the original text was processed to take away function words in ROSTCM6.0 as outlined by the place word, place word, nature word, organization word, number unit, along with other components to construct a custom segmentation dictionary. Ultimately, land use type, management organization, land plot location, land plot region, business enterprise situation, and other fields had been sorted out. two.three.2. Spatial Statistics The study matched the web page extracted from the land management records with the obtained base map and converted it in to the present internet site. ArcGis10.two was employed to transform the land data into discrete point facts with attributes. This study has obtained the land location details but, as a result of limitation of historical literature, it lacked specific spatial configuration data. Thus, the map can’t be directly drawn, along with the plot areas had been used as the pointing supply data. By utilizing ArcGis10.two for nuclear density statistics together with the plot region because the weight field, this study, to a specific extent, reflects the space distribution of plot size and quantity. It additional analyses the range and core of many royal land plots. The formula of kernel density estimation (KDE) is expressed as: f n (x) = 1 hni =wi knx – xi hnEquation: k – xi represents the nuclear density equation; h represents the search hn range and h 0; n represents the number of plots points inside the search variety; wi represents the corresponding weight assigned to every single plot point xi . 3. Final results 3.1. Land Use 3.1.1. Analysis with the Land Use Forms The research in the land use types is primarily based around the facts regarding the land nature and place functions retrieved from recorded Tenidap Epigenetics documents. Within this analysis, the grounded theory [23] is employed to merge the most simple varieties till they could no longer be merged, a system of qualitative analysis, and the major purpose is to establish a theory primarily based on empirical information. The investigation goes on to calculate the total location of each and every form after 22 simple sorts, 15 subdivisional varieties, and five VBIT-4 Biological Activity heading types are determined. In the method of merging the forms of plots, some fundamental forms are classified singly as subdivisional kinds. Ultimately, 15 subdivisional forms is often merged into 5 heading varieties for an intuitive evaluation. The spatial quantitative evaluation from the investigation mainly focuses on the land kind I (heading sort) and II (subdivisional variety) (see Table 1).Land 2021, ten,8 ofAs production land, most farmland is utilized for rice and wheat planting as well as a compact quantity for pastures. According to the water condition, farmland is classified into rice land and dry land. The latter is further classified into the categories of wheat field, pasture field, and dry field which can be absolutely free for any type of planting. Among these, the wheat and dry field are charged rent plus the pasture field is court-planted. The water land refers to water plantation regions inside the Forbidden City, the palaces, and the Chang River. It might be subdivided into river land, cattail field beside the dockyard, and lotus pond, with each scenic and financial value. Each cattail field and lotus pond subdivisions are charged rent, as well as the only distinction involving the two is that only lotus is usually planted within the lotus pond.Table 1.
