JOHANNESBURG, FEB. 10 -- Despite President Frederik W. de Klerk's recent announcement that several basic apartheid laws will soon be repealed, government leaders have made clear that virtually no fundamental changes giving blacks a role in government are contemplated in the immediate future.

De Klerk announced Feb. 1 that legislation will be introduced to repeal laws restricting where and how South African blacks live, but the changes are unlikely to meet the expectations of the black majority and could fuel demands for further reform.

Since the announcement, top government ministers have clearly indicated that the segregated tricameral Parliament and its racially separated voting system that excludes blacks entirely will not be changed until a new constitution is negotiated several years from now.

Black nationalist groups say this is the essence of the apartheid system of segregation and discrimination, and until blacks are granted the right to vote and be elected to Parliament, they will remain excluded from the political process.

These groups say the reforms amount to an attempt by whites to keep South Africa safe for continued segregation and white privilege in new guises, and could heighten frustration among blacks.

De Klerk made his announcement in Parliament on Feb. 1, saying legislation would be introduced to scrap the Land Acts of 1913 and 1936, which reserve 87 percent of the country's land for the white minority, as well as the 1984 Black Communities Act, which enforces rigid segregation.

He also said the Population Registration Act, which separates all South Africans into racial groups for living, voting and identification purposes, would be eliminated.

The United States and the European Community welcomed de Klerk's announcement, and some governments indicated that sanctions imposed to protest apartheid could now be lifted. The African National Congress, South Africa's largest black nationalist group, said the reforms would have little impact on the daily lives of blacks here and urged foreign governments not to "be hasty" in ending sanctions.

Ever since de Klerk's announcement, Pretoria's new buzzword in discussing the reforms has been "community rights." But the minister of constitutional development, Gerrit Viljoen, admitted last week in a briefing that "there isn't really much difference" between "community rights" and "minority rights," a concept blacks regard as a euphemism for maintenance of white privileges.

The ministers also said no changes will be made during the interim period in the government's "own-affairs" policy, in which whites, Indians and mixed-race Coloreds run separate education, health and other services.

The only hint that some radical change might occur in the near future, at least at the local level, came from Planning and Provincial Affairs Minister Herus Kriel. He said formation of a single municipal council and voting for its members on a common voters' roll that includes blacks would be possible now -- if neighboring black and white town councils agreed to such steps in negotiations.

Viljoen, however, seemed opposed to such voting, saying the issue of giving blacks the vote was "a basic and fundamental matter of a new constitution" that could not be negotiated "in a piecemeal, interim, transitional way."

Viljoen said the Land Acts of 1913 and 1936 will be repealed in the current session of Parliament, but he did not indicate what would replace these laws or suggest any massive restitution of land to its original owners.

He also acknowledged that "much more" was necessary than just the repeal of the two acts to ensure that all South Africans have equal access to land and that existing private property and title rights are protected.

However, according to Kriel, there are "no plans underway" to provide compensation for land and property forcibly taken from black individuals and tribes by the government. He also dismissed "so-called affirmative action" as a failed approach to correcting social wrongs in Western countries that would not be adopted here.

About the best non-whites could hope for, at least those with sufficient money, was access to loans from the Land Bank to enable them to buy farms and plots of land just like whites do now, according to Kriel and other ministers.

While de Klerk also announced that the Group Areas Act of 1966 will be scrapped, he left unclear just what would happen afterward to promote integration, if anything.

According to Kriel, the integration of segregated neighborhoods would be left to "market forces" to resolve over time. "We're not going to try and force through some gimmick that neighborhoods go black or go white," said Kriel.

He acknowledged that the repeal of this act would do little to resolve the housing problem for blacks "because the majority of black people in this country do not form part of the higher-income group" with money to buy homes in white areas.

"We will have to live with informal housing for a long, long time to come," he said. "We haven't got the money. It is just not possible to provide formal housing for everybody in this country of ours."

The government, he said, intends to allow each community to set its own "standards and norms" short of discriminating on the basis of color, race or creed. Kriel said these would include regulating such things as housing density, health regulations and animal ownership.

The only piece of proposed new legislation dealing specifically with racial discrimination -- which was not mentioned by any of the ministers -- is the General Law Amendment Bill. Press reports say it prohibits any discrimination on the basis of race or class in any land or property transactions.

The biggest surprise in de Klerk's announcement was that the Population Registration Act of 1950 -- which separates all South Africans into four major racial groups at birth, affecting virtually all aspects of life -- would be repealed. But it will be replaced by "temporary transitional measures" keeping the present tricameral Parliament in place and assuring that any by-elections will still be on the basis of separate voters' rolls.

Ministers also made clear that as long as the apartheid Parliament remains in place, there is unlikely to be any progress toward establishing a single national education system, a chief demand of blacks.

"The {education} system as we know it is part and parcel of the constitution," Minister of National Education Louis Pienaar told reporters. "If you want to change that, you need to change the constitution."

Similarly, Minister of Law and Order Adriaan Vlok quashed expectations of fundamental changes in the Internal Security Act, notably its Section 29 which allows the police to detain people for unlimited time without trial. Vlok said this was needed to combat "terrorism" from both white and black extremists opposed to the reform process.

Saying that the police had solved 90 percent of white right-wing terrorist cases, he said this would not have been possible "if we were not able to use Section 29 to detain people and question them until they give satisfactory replies to our questions."
