In a preferred embodiment, a specific repair procedure for land areas is provided, please refer to table 1, table 1 is an exemplary table of land data provided in an embodiment of the present invention.
Table 1 example plot data table
As shown in Table one, the paddy field is judged, the accumulated value of the original accumulated value of the area of the land occupation is 2849 square meters, and no adjustment is made in the case that the accumulated value of the area of each land occupation is identical to the accumulated value of each land occupation. The area units are square meters, and the following are the same.
Then, the total area of other cultivated lands is judged, the sum of the area accumulated value of the original occupied land is 31138, and the sum of the area accumulated value of the original occupied land and the sum of the area accumulated value of the area accumulated land of each land is 31138, and the area accumulated value of the original occupied land is equal to the sum of the area accumulated value of the original occupied land and the area accumulated by other cultivated lands, namely, the total area of cultivated lands is 33987.66, the sum of the area accumulated by other cultivated lands is 33988 (first trimming result), the determined trimming post-land area 2849 (first trimming result) is subtracted, the actual result value is 31139 (first calculating result), and the difference between the actual result value and the trimming pre-land trimming area 31138 (trimming value of the second grouping of the area analyzed result) is 1, so that the difference is needed to be made. As shown in Table 1, according to the sequence from large to small, 1 is added to the land with the largest area, and so on, if the minimum land is finished with one square, the adjustment value is still remained, and the adjustment is restarted from the land with the largest area, so that the cycle is performed.
According to the priority ranking, the adjustable area condition is then judged, (the adjustable area condition is not a type of land which is an attribute attached to other types of land, whether the field of 'land remark' is 'K' in the land pattern data is judged) the total original occupied area and the total area before trimming and after trimming are same as 93523 (trimming value of the third grouping of occupied pressure analysis results), but the paddy field area and other cultivated areas are considered, the original occupied area of the paddy field, the original occupied area of other cultivated areas and the adjustable area are summed together in the same way, the trimming area is 127510 (second trimming result), the determined paddy field area and other cultivated areas 33988 (first trimming result) are subtracted, the actual result value is 93522 (second calculating result), and the trimming area 93523 before trimming and trimming before trimming (trimming value of the third grouping of occupied pressure analysis results) are different by 1 according to the principle, so trimming is required, and the area is reduced by 1 on the largest land block according to the principle, as shown in table 1.
After the adjustment, the original land codes of the land block with the adjustment, such as 021 orchards, need to be recorded, and when the adjustment of the corresponding orchards is related later, the land block needs to be removed first and does not participate in adjustment calculation.
And similarly, judging the conditions of the construction land and other land areas, and directly judging the conditions of the other land areas without occupying the construction land in the example table.
When the condition of the last group area adjustment is judged, the sum of areas after the previous groups of adjustment is directly subtracted from the total area (first addition result) of the input project land parcels (second addition result), a first subtraction result is generated, the first subtraction result is compared with the sum of areas before adjustment of the last group (occupation analysis result of a fifth group), and adjustment is carried out when a difference exists.
